Horse training: Are you a good boss?

Horses human face upward the same kinds of stresses in addition to frustrations every bit humans inward their day-to-day lives. It is trivial wonder they sometimes experience the strain. Researchers are taking an involvement inward how horses grapple alongside the pressures of training.
Most people know entirely likewise good the consequences of likewise much stress inward their daily lives. Perhaps it is from long in addition to arduous hours of work, or a boss who is likewise picky in addition to demanding.
Researchers have got inward recent years started looking at stress inward the workaday lives of horses, both inward preparation in addition to nether saddle across a raft of disciplines.
Can horses buckle nether the same kinds of stresses that deport on humans?
The answer, it seems, is yes, in addition to the trigger points would appear to live similar: learning hard novel tasks, dull day-to-day routines, poor relationships, negative reinforcement, insufficient rewards, in addition to a troublesome boss (trainer).
All are stress factors for horses, researchers have got shown. They tin atomic number 82 to frustration in addition to neurosis inward horses, behavioural scientists suggest.
Researchers inward Europe have got been leading the way inward probing the preparation stresses faced past times horses.
Why should horses acquire stressed inward the inaugural of all place?
Professor Martine Hausberger in addition to her swain researchers inward French Republic banknote that horses, similar people, are often asked to piece of occupation on a daily basis, involving “interpersonal” interactions non entirely alongside other working horses but also alongside a “boss” – the human who manages or rides the animal.
“Work sessions are based on training, using to a greater extent than often negative reinforcement or penalty than positive reinforcement,” they noted inward the findings of recent research.
“Physical in addition to emotional constraints depend also on the type of piece of occupation performed. Negative consequences of some practices, leading to physical in addition to behavioral resistances, opened upward conflicts in addition to tensions during the piece of occupation sessions have got been described for some time.
“Conflicting signals given past times the passenger (urge forwards alongside the legs in addition to maintain restraining through the mouth/bit) may atomic number 82 the Equus caballus to frustration in addition to neurosis.
“Finally, horses are asked to suppress emotional reactions from their early on stages of piece of occupation on, every bit such reactions may live reverse to the performance expected (dressage competition) or considered unsafe for the passenger (such every bit bucking).
“Few studies, however, enquiry the possible durable effects of such piece of occupation stressors – interpersonal conflicts, suppressed emotions, physical constraints – on the daily life of horses exterior the piece of occupation sessions.”
Hausberger, who directs the Department of Ethology at the University of Rennes 1 inward France, suggests negative experiences linked to preparation could atomic number 82 to chronic states where horses “switch off”, becoming unresponsive in addition to apathetic – states described inward humans inward cases of work-related burnout.
Abnormal repetitive behaviours inward horses are thought to live a way for animals to grapple alongside an unfavourable stress-inducing environment.
So what would seem to live areas of greatest stress?
An Austrian study confirms that starting a Equus caballus nether saddle causes stress, which rises markedly during the inaugural of all fourth dimension a passenger gets on the horse.
It seems probable that the Equus caballus interprets the inaugural of all mounting of a passenger every bit a potentially lethal assault past times a predator, from which it is unable to escape, the researchers suggest.
“In addition, the passenger is exterior the horse’s acre of vision, which presumably exacerbates the problem,” researcher Alice Schmidt said.
Schmidt in addition to others at the University of Veterinary Medicine, inward Vienna, inward a study reported inward the journal, Hormones in addition to Behavior, measured stress past times examining the horses’ heartbeats in addition to the levels of the stress hormone cortisol inward their saliva.
In looking at the heartbeat, she considered non entirely their frequency but also the short-term fluctuations inward intervals betwixt the beats, which have got previously been shown to live a adept indicator for stress.
Schmidt used three-year-old horses at the start of their initial preparation regimes. Not surprisingly, she found the start of preparation was a stressful period.
“The initial piece of occupation on the lunge caused entirely a moderate amount of stress but the stress aeroplane rose markedly when the passenger inaugural of all mounted,” she reports.
This was revealed past times an immediate increment inward heartbeat in addition to inward the fluctuations inward intervals betwixt private beats, every bit good every bit past times the release of cortisol into the saliva.
When the Equus caballus in addition to passenger walked or trotted forward, the aeroplane of stress decreased somewhat.
“It seems every bit though the Equus caballus adapts speedily to the thought of existence ridden in addition to that – every bit is the illustration for humans – exercise may aid salvage stress,” she says.
The extent of stress caused past times mounting was found to decrease gradually every bit the Equus caballus was trained, provided the preparation was existence done correctly.
Fellow researcher Jörg Aurich cautions that a lack of tending or an wrong authorities inward early on preparation could crusade long-term impairment to the human relationship betwixt a Equus caballus in addition to its rider. It could thus preclude a sports Equus caballus reaching its total potential, every bit good every bit causing the brute unnecessary anxiety.
Although Schmidt’s results clearly demo that the initial preparation of a sport Equus caballus stresses the animal, Schmidt has some reassuring words for trainers in addition to riders.
“The stress caused past times existence ridden for the inaugural of all fourth dimension is nowhere close every bit much every bit that caused past times existence transported past times road. And if yous are gentle in addition to careful when yous start to prepare a immature horse, it volition shortly acquire used to you.”
In France, researchers extended stress enquiry to the role of temperament inward training.
They found that both stress in addition to temperament influence the learning powerfulness of horses, but it is non altogether simple.
The scientists used 49 woman someone Welsh ponies aged around seven, randomly divided into iii groups.
One grouping of fifteen was stressed before a learning task, the 2nd grouping of fifteen was stressed after the same learning draw in addition to the tertiary group, of nineteen animals, was non stressed at all.
The stress involved exposure to xx unpredictable abrupt events, from unfamiliar objects to loud sounds in addition to abrupt movements.
Each of the animals was assessed beforehand for temperament using a method adapted from previous researchers. It assessed 5 dimensions – fearfulness, grouping sociability, reactivity to humans, aeroplane of locomotor activity, in addition to sensitivity to touch.
The learning draw involved preparation each Equus caballus to touching a cone on the Earth alongside its olfactory organ for a nutrient reward. The learning draw was repeated a calendar week after to create upward one's hear whether at that spot was whatever differences betwixt the iii groups.
The study, led past times Mathilde Valenchon in addition to published inward the open-access journal, PLoS ONE, showed that learning performances varied according to the exposure to stress.
Horses stressed before the learning draw tended to perform to a greater extent than successes at the outset of the learning session than the non-stressed horses.
Eight days later, during the re-learning session, the non-stressed animals improved their performance.
Contrary to the non-stressed group, the horses that had been stressed after the learning task, and, to a lesser extent, those stressed before, did non significantly amend their performance.
The researchers found that temperament influenced learning performance, but entirely when the learning or re-learning performances were affected past times stress, suggesting that temperament had trivial influence on learning powerfulness provided lessons occurred inward a stress-free environment.
They found that piece straight exposure to a stressor tended to increment learning performance, the solid ground of stress induced past times the retention of a stressor during efforts to re-learn or reinforce the draw impaired performance.
Further, the negative effect of a solid ground of stress on re-learning the draw appeared to live stronger when exposure to the stress occurred after rather than before the learning session.
The results, the researchers said, suggested that stress impaired to a greater extent than cognitive abilities inward fearful horses than inward less fearful horses.
“The acquaint study constitutes the inaugural of all evidence that stress modulates the influence of temperament on cognitive abilities inward horses,” Valenchon in addition to her colleagues reported.
Valenchon, inward some other study, explored the effects of stressful situations on the working retention of horses, testing the powerfulness of thirty Welsh pony mares to cry back inward which of ii buckets they would uncovering a carrot.
A researcher dropped a carrot inward i of the buckets inward sight of the mares. Each Equus caballus was made to hold off betwixt cipher in addition to xx seconds before existence allowed to the bucket to retrieve the carrot.
In a calm setting, the horses were found to have got an average working retention of sixteen seconds.
However, when the testing was performed nether stressful atmospheric condition – involving the likes of a barking Canis familiaris in addition to a waving canvass – they performed much worse.
The mares also underwent temperament assessments, alongside the researchers finding the to a greater extent than fearful horses performed fifty-fifty worse nether stressful conditions, despite to a greater extent than often than non performing best inward the same essay out inward a calm environment.
Researchers have got also found that different disciplines have different levels of stress inward horses.
Findings from French enquiry quest that dressage in addition to high-school piece of occupation create higher levels of stress inward horses than the likes of jumping, eventing in addition to vaulting.
The scientists from the University of Rennes 1 explored whether the daily piece of occupation to which many horses are exposed could outcome inward the same sorts of stresses experienced past times people inward their piece of occupation environments.
The findings, published inward PLoS ONE, quest that horses, similar people, human face upward stresses inward their daily life involving troublesome human bosses, hard interpersonal relationships, undue negative reinforcement in addition to poor rewards.
Such negative experiences linked to preparation could atomic number 82 horses to switch off, becoming unresponsive in addition to apathetic – the equine equivalent of work-related burnout inward people.
The researchers – Hausberger, Emmanuel Gautier, Véronique Biquand, Christophe Lunel, in addition to Patrick Jego – laid almost studying 76 French Saddlebred horses stabled at the Ecole Nationale d’Equitation inward Saumur.
The horses, aged 6 to 15, were all geldings in addition to housed inward the same conditions, spending 23 hours a 24-hour interval inward their stables. They received the same diet. The entirely departure was inward the variety of acre of study they performed each 24-hour interval for an hour.
The scientists monitored the horses inward their stables for behaviors called stereotypies – abnormal repetitive behaviors which serve no useful function. These include repetitive oral fissure movement, caput tossing or nodding, wind-sucking, cribbing in addition to weaving.
They found that the type of piece of occupation performed past times the horses each 24-hour interval had a meaning influence on the prevalence in addition to types of undesirable traits shown.
“To our knowledge, this is the inaugural of all evidence of potential effects of piece of occupation stressors on the emergence of abnormal behaviors inward an brute species,” the researchers noted.
“It raises an of import draw of thought on the chronic impact of the piece of occupation province of affairs on the daily life of private [horses].”
The researchers found that 65 of the 76 subjects performed some type of stereotypy.
The horses were categorised every bit doing i of iii kinds of work:
- Jumping/eventing/advanced-riding-school.
- Dressage/high-school.
- Vaulting.
Vaulting horses appeared to live the to the lowest degree prone to stereotypies whereas dressage/high-school horses presented the highest incidence of such undesirable traits. Several of these horses performed ii or to a greater extent than types of stereotypies.
They also performed the stereotypies considered to live to a greater extent than serious – cribbing, windsucking in addition to caput shaking.
The authors pondered why dressage appeared to crusade the most stress.
“Dressage in addition to high schoolhouse both await horses to restrain from expressing emotions in addition to set a strong physical constraint on the movements,” they noted.
“Moreover, cases where orders tin live conflictual are to a greater extent than frequent hither every bit the restricted gaits are often obtained past times refraining motion through the reins in addition to flake piece pushing forwards the Equus caballus through the legs.
“Therefore both physical in addition to interactional stress tin explicate the high prevalence in addition to types of stereotypies observed inward these horses.
“Jumping, eventing or educational activity horses were trained to a greater extent than to convey long strides piece moving forwards inward a less ritualised posture. These horses performed to a greater extent than repetitive licking or biting of environmental structures.”
These, they said, are often considered to live early on stages of stereotypy.
“Whether these horses would develop to a greater extent than serious stereotypies alongside fourth dimension appears unlikely every bit they remained nether these atmospheric condition for at to the lowest degree i yr in addition to often more. Maybe they were reacting mainly to the full general unsuitable atmospheric condition (social separation …) they were housed in.
“Finally, vaulting horses appeared the to the lowest degree prone to perform stereotypies in addition to these were restricted mainly to natural language play. Vaulting horses had been chosen for their serenity temperament in addition to spent their piece of occupation fourth dimension turning inward circles, alongside vocalism orders.
“Interpersonal conflicts alongside the human are rather limited every bit they are only required to maintain regular in addition to tardily paces, piece accepting humans to brand movements on their backs. Their originally quieter temperament may also brand them to a greater extent than resistant to possible piece of occupation stressors every bit observed inward humans.”
The authors pointed to before enquiry suggesting that caput shaking may live a lasting effect of strong flake action, resulting from impairment to the trigeminal nerve, every bit riders piece of occupation to maintain their horse’s caput down.
This would explicate why headshaking in addition to nodding were performed to a greater extent than often past times dressage horses every bit for most of their working fourth dimension they have got to maintain their necks flexed inward restrained gaits, they said.
“Although some piece of occupation stressors involved hither may live specific to equine work, others are clearly shared alongside other species, including humans: emotion suppression, interpersonal conflict, physical demands, lack of vantage in addition to negative time to come expectancy that are associated alongside depression inward humans.
“The acquaint study opens clearly novel in addition to farther lines of thought about, on i hand, the causation of abnormal repetitive behaviours, on some other manus the effects of piece of occupation stressors non entirely on good known expressions of psychological disorders such every bit depression or burnout but also on the possible emergence of abnormal behaviour.
“The really controlled restricted locomotion allowed inward dressage in addition to peculiarly high-school horses associated alongside rapid transitions may explicate an increment of reactivity, peculiarly when flake pressure level in addition to spurs have additional aversive stimulations.
“The higher emotional responses of dressage horses inward emotional tests render farther back upward for this hypothesis. Collected gaits may also live physically really demanding in addition to these difficulties may frustrate the horse, but also its passenger who tin transmit additional nervousness.”
The authors noted that other factors tin live involved inward evolution of stereotypies, including roughage availability, diet, social deprivation, lack of exercise in addition to genetic susceptibilities. The length of fourth dimension spent inward stalls may also have got an influence.
However, the results clearly showed that the acre of study existence performed past times the Equus caballus influenced the aeroplane to which they showed undesirable traits.
“We showed that, for a diverseness of reasons (physical, emotional …) the limited fourth dimension spent alongside humans mightiness deport on the remaining daily life of the horses.
“This may good live truthful for other situations such every bit handling, feeding, transporting animals. These results also get upward the enquiry of how different types of repetitive movements may develop.
“While some may live explained past times lasting effects of physical constraints, others may emerge through chronic stress.”
Of the 76 horses, 10 undertook eventing, nineteen were demo jumpers, 7 worked inward an advanced riding school, 17 performed dressage, sixteen were high schoolhouse horses in addition to 7 were used inward vaulting.
In a related theme, British enquiry showed the importance of matching a horse’s temperament to different equestrian disciplines.
The study involved a comprehensive review of psychological factors affecting equine performance.
The research, published inward the open-access mag BMC Veterinary Research, explored issues surrounding training, contest surroundings in addition to practices, in addition to how the psychology of Equus caballus mood, emotion in addition to temperament could live used to heighten performance.
British researchers Dr Sebastian McBride, from the Royal Agricultural College, in addition to Professor Daniel Mills, from the University of Lincoln, looked at how electrical flow behavioral enquiry in addition to already-established behavioral modification techniques could live applied to heighten the performance of contest horses.
This included matching a horse’s temperament to different equestrian disciplines. For example, flightiness tin live adept for racing but detrimental for dressage.
“Another of import consideration is the horse’s mood in addition to emotional reaction,” McBride said.
“Although all of these have got an intrinsic baseline observable inward the young, untrained horse, they tin live influenced past times preparation in addition to they are also dependent on the interaction betwixt passenger in addition to horse.
“Competition riders are good aware how a foreign environment, in addition to nerves on contest day, tin deport on their horse’s performance.”
Mills continued: “The increased competitiveness in addition to performance aeroplane of equestrian sport agency that for each Equus caballus in addition to passenger pair, physical in addition to psychological demeanour must live taken into consideration when designing preparation atmospheric condition in addition to increasing motivation to perform at the optimum aeroplane of athletics.
“They must also live applied to reducing over-emotional reactions on contest 24-hour interval and, given the trained horse’s high motivation to succeed, to decrease whatever negative experiences at competitions which may otherwise impact on time to come events.”
The researchers noted that increased competitiveness in addition to the performance aeroplane inward sport right away required that individuals in addition to teams must give over a substantial amount of fourth dimension to their respective disciplines.
The distich identified areas inside the electrical flow performance Equus caballus manufacture where known behavioral enquiry in addition to behavioral modification techniques could live applied to heighten the performance of those animals.
These included ensuring optimal environmental atmospheric condition for the horse, in addition to using behavioural modification techniques to:
- Sufficiently motivate the brute to perform the right athletic behaviour.
- Reduce overly reactive behaviour inward anticipation of the competitive event.
- Reduce emotionally reactive behaviour to novel stimuli associated alongside the competitive event.
- Reduce motivated behaviors inward response to stimuli associated alongside contest events that are a outcome of previous negative experiences linked to those stimuli.
The distich noted that, despite its obvious importance, at that spot was remarkably trivial enquiry into whatever aspect of the psychology of equestrian performance.
They said psychological factors existed at iii inter-related but separate levels: temperament, mood in addition to emotional reaction.
Temperament existed every bit a relatively stable constituent inward adult life, they noted, having been shaped past times genetic makeup in addition to early on experience, whilst mood described a to a greater extent than temporary psychological state.
Emotional reactions were the most tightly stimulus-bound affective states in addition to the shortest lived temporally, describing the to a greater extent than immediate response to a situation.
“If mood is negative in addition to so at that spot is a higher probability of negative emotional reactions to a given situation,” they wrote.
“Whilst at that spot is a growing literature on temperament inward horses, at that spot is silent really trivial scientific piece of occupation on the emotional reactions of horses in addition to almost none on the assessment of moods.
“It is nonetheless of import to appreciate that although it is hard to study these phenomena, this does non hateful that they are non of import in addition to for certain that they do non exist.”
In their review of temperament, they said it was clear that to a greater extent than validation-type enquiry was required to stair out early on temperament traits alongside a thought to matching them alongside equestrian disciplines.
They said both mood in addition to emotional solid ground were crucial inward determining how a Equus caballus perceived in addition to reacted to its surroundings in addition to thus how it would perform inside a preparation in addition to contest environment.
“Positive mood is essential for all disciplines, but the optimal emotional solid ground leading to optimal emotional arousal tin vary betwixt disciplines in addition to betwixt horses, every bit inward the illustration alongside humans,” they said.
“Over-reaction every bit the outcome of high emotional arousal is detrimental to performance in addition to is heavily influenced past times prior preparation techniques in addition to also the emotional solid ground of the rider.
“More extensive enquiry is required inside both of these areas,” they said.
The distich said many horses may neglect inward contest because of the departure betwixt the preparation in addition to contest environments in addition to thus the lack of preparation to generate appropriate emotional in addition to behavioral responses to competition.
“It follows, therefore, that i of the most of import factors at the outset of preparation is to ensure that the private brute is sufficiently motivated to perform.
“Interestingly, inward human sports performance psychology, this motivation either to succeed or to avoid failure is so enhanced inward some individuals that it often develops clinically every bit obsessive-compulsive characteristics, referred to every bit perfectionism.”
Motivation to larn is also heavily affected past times the learning environment, they said, inward particular the duration of the preparation session in addition to how often those sessions occur on a daily or weekly basis.
“The aeroplane of motivation to perform volition live determined past times the type of learning taking house (for example, negative versus positive reinforcement) in addition to the complexity of the task.”
In this respect, much to a greater extent than enquiry was needed to constitute optimal preparation schedules for specific equestrian tasks, they said.
To compete successfully inward competition, regardless of the discipline, it was of import that the Equus caballus is highly motivated to perform the specific athletic activity at the outset of both preparation in addition to competition.
“The performance Equus caballus also needs to live motivated at the fourth dimension of competition, but non to the extent that whatever restriction of that motivated demeanour has a negative effect on the animal’s physiological or psychological state.
“Highly motivated horses, however, tin live exposed to behavioral modification techniques inward lodge to attenuate specific unwanted behaviors, but the brute must live capable of responding to these techniques inward a positive way.
“Modification techniques tin also live applied to highly reactive horses that are responding to novel stimuli or previous negative experiences, but over again those individuals demand to live responsive to those techniques.”
Not so negative
A Danish study that looked at negative reinforcement inward preparation reveals that it may live beneficial inward getting horses used to unfamiliar objects, but comes alongside a warning over stress responses inward animals.
The results of the study past times Janne Winther Christensen, of Aarhus University, was published inward the Equine Veterinary Journal.
Christensen said the powerfulness of horses to acquire used to novel objects influences security inward the horse-human relationship. However, the effectiveness of different ways of habituating horses had non been investigated inward detail.
Christensen laid almost investigating whether horses showed increased stress responses when negatively reinforced to approach novel objects, compared to horses that were allowed to voluntarily explore the objects.
The enquiry also laid out to uncovering whether negative reinforcement aided object habituation.
Twenty-two 2 to 3 yr former Danish Warmblood geldings were used inward the study.
Half were negatively reinforced past times a familiar human handler to approach a collection of novel objects inward a essay out arena. The other one-half of the horses – the voluntary grouping – were individually released inward the arena in addition to were gratis to explore the objects.
On the side past times side day, the horses were exposed to the objects over again without a human to allow the charge per unit of measurement of habituation to live investigated.
Behavioural in addition to heart-rate responses were recorded during the study.
Christensen found that all horses inward the voluntary grouping initially avoided the unknown objects, whereas the handler was able to acquire all negatively reinforced horses to approach in addition to stand upward side past times side to the objects inside the inaugural of all two-minute session.
The negatively reinforced horses had a significantly longer duration of alertness in addition to a higher maximum take in charge per unit of measurement inward the inaugural of all session. On the next day, however, the negatively reinforced horses spent significantly less fourth dimension investigating the objects in addition to approached a feed container, placed side past times side to the objects, faster than the voluntary group, indicating increased habituation.
Christensen found that piece the approach using negative reinforcement aided habituation inward immature horses to approach novel objects, at that spot was an increased stress response during initial exposure.
“Although negatively reinforced approach appears beneficial for habituation, the physical care for should live carefully managed due to increased stress responses inward the Equus caballus which may constitute a security risk,” Christensen said.
“Further experiments should aim to investigate differences inward stimulus intensity.”
Ironically, it seems that horses properly trained for the contest surroundings do non endure from i of the curses of human performance – phase fright.
Austrian enquiry suggests horses do non endure from phase fright inward forepart of an audience – but their riders most for certain do.
The researchers laid almost determining whether the familiar signs of phase fright, alongside all its nasty manifestations such every bit rapid pulse, dry out mouth, shaky voice, blushing in addition to sweaty palms, affected horses.
Was the status restricted to humans, they wondered? How do animals react to the presence of human audiences?
Professor Christine Aurich in addition to her squad at the University of Veterinary Medicine, inward Vienna, tackled the questions.
Their enquiry confirms that Equus caballus riders endure to a greater extent than stress when performing inward forepart of an audience than when practising for the event, but demo that the horses themselves react identically whether or non spectators are present.
The horses in addition to their riders thus perceive the challenges of competing inward equestrian events differently, the scientists concluded.
Little attending has been paid to the effects on riders, the researchers noted. That was surprising, they said, given that equestrian sports relied on the closed co-operation betwixt the animals in addition to their riders.
The enquiry was undertaken past times Mareike von Lewinski inward Aurich’s group, together alongside colleagues at the academy in addition to at the Ecole Nationale d’Equitation inward Saumur, France.
The scientists measured the changes inward diverse stress-related parameters, such every bit the aeroplane of stress hormones inward saliva in addition to the regularity of the pulse, inward horses in addition to their riders when the animals were ridden inward a particular demo programme.
The measurements were taken both when the presentation was completed inward forepart of almost a grand spectators in addition to when the riders practised beforehand without whatever spectators.
The results were compared to assess how the riders in addition to their mounts responded to the presence of the audience.
In draw alongside previous experiments, the researchers could uncovering symptoms of stress – higher cortisol concentrations inward the saliva in addition to to a greater extent than irregular heartbeats – both inward horses in addition to inward their riders during the study.
But the riders showed significantly higher levels of stress when an audience was present, confirming what was suspected – participation inward equestrian events is associated alongside phase fright, fifty-fifty inward experienced riders.
There are many reasons why riders mightiness live to a greater extent than stressed when performing inward forepart of an audience than when practising. As Aurich says: “They are entirely human, after all.”
In contrast, the horses appeared non to live affected past times the presence of spectators: their reaction to the course of educational activity was essentially independent of whether an audience was acquaint or not.
In other words, the horses in addition to their riders respond differently to the challenges posed past times performing for spectators, alongside the horses non suffering from the increased levels of stress shown past times their riders.
The results imply that the riders do non communicate their heightened anxiety to the animals.
The lack of transfer of emotions betwixt passenger in addition to Equus caballus was completely unexpected.
Aurich concedes: “We started alongside the supposition that the rider’s stress would deport on his Equus caballus but this does non seem to live the case.
“Nevertheless, nosotros should deport inward hear that nosotros were working alongside experienced horses in addition to highly skilled riders: our findings cannot live generalized to inexperienced riders, who mightiness live less able to preclude their horses from existence stressed past times the situation.”
