Separation Distress
Separation related problems are extremely common in domestic horses, this is most likely due to widespread weaning practices where horses are weaned early and abruptly rupturing maternal bonds ( McMilan,2016, Rybovak,2022).This then can impact a horse throughout their life. It is not uncommon for horses to experience social flux on livery yards where horses are frequently added or removed from the group or in some cases kept in isolation which can exacerbate separation distress. Early in life a horse’s dam acts as a secure base from which to explore the world and the mare/foal bond is crucial for influencing future relationships both with other horses and humans. It is crucial to understand that separation anxiety is a normal response to a dependent experiencing lengthy or prolonged separation from their main attachment figure (carer), however, if it is excessive it can interfere with an individuals ability to cope.
Separation distress can give rise to a range of emotions including anxiety, fear and even frustration as the horse seeks to re-connect with their carer or main attachment figure. Frustration occurs as the horses attempt to reach their companions are thwarted.
Social panic, bonding and attachment is opioid-mediated, so separation and social isolation produce an analogous response to that of opioid withdrawal (Panksepp et al,2005,Panksepp,2011,Eisenberger,2012,McMilan,2016). In other words, separation is physically painful. True separation distress extends far beyond simple frustration or anxiety at being on their own, instead it is a fear or aversion to the absence of an attachment figure that triggers a panic like response. Separation distress like all other struggles horses may have are multifaceted and may be rooted in a range of causes including but not limited to
🐴Epigenetics
🐴Genetic predisposition
🐴Trauma
🐴Previous experiences in particular those early in life including early weaning and the breaking of maternal bonds
🐴Early life stress
🐴Attachment ruptures
🐴Temperament
🐴 Breed traits
🐴Pain or pain memory
Separation anxiety can manifest in a range of ways including
🐴Vocalisation
🐴Fence walking
🐴Increased movement
🐴Increased urination and/or defecation
🐴 Panic
This panic response from an evolutionary standpoint is understandable as to a young mammal the loss of their dam and social group poses a threat to life.
Horses are a highly gregarious species who are extremely dependent on each other in order to survive and thrive. They also likely form bonds with human caregivers, however, research on this is sparse in comparison to the dog-human bond. The limited research that has been conducted points to attachment difficulties associated with the human caregiver occur when the caregiver is inconsistent in their behaviour such as the sporadic use of punishment (Lundberg et al,2020) This echoes the human literature where attachment problems occur as a consequence of disorganized attachment as opposed to hyper-attachment this is commonly seen in other animals such as dogs.
Keeping horses in isolation is also common practice which may lead to the development of separation distress in some cases (Newberry & Swanson,2008,Lansade et al,2022) In comparison to other species we have less understanding of how horses form and maintain attachment bonds.
Attachment behaviours include: -
🐴Proximity Seeking: Closeness to the attachment figure in order to gain a sense of security and protection.
🐴Secure Base: This is where the attachment figure provides a secure base from which the individual can leave the attachment figure and explore the world. This extends to other relationships not just that of the mare/foal bond.
🐴Safe Haven: The attachment figure provides a sense of security during times of stress or if an individual is struggling to cope.
Disturbances of social groups and contexts has been researched on other species such as elephants and given horses face similar denials of or disruptions to equine social structures it is possible that this also exists for horses and may influence their behaviour and ability to cope (Manrique et al,2022).
Social behaviour in horses involves the use of MUTUAL communication between all herd members. Horses communicate via body language and behaviours through the giving and responding of signals to develop a mutual language between them. Their behaviours gain meaning through being given consistently and predictably over time. Each individual horse has their own comfort zone or bubble around them and they communicate who is or is NOT allowed to share their space (Bartlett et al,2022, Woltee et al,2018, Kieson et al,2023) Friends or preferred conspecifics will be allowed closest but other horses they would prefer to have further away. It is important not to confuse this with resource sharing, guarding or dominance. A horse’s bubble can be influenced by stress, pain, illness or tiredness among other factors. Recent and emerging research suggests horses display social bonds through: -
🐴Proximity
🐴Mutual movement and synchrony
🐴Mutual touch
Supporting horses who are experiencing separation distress involves a combination of ensuring their social, physical and emotional needs are met, careful management to ensure that they aren’t put in situations they cannot cope with and the gradual titration and pendulation of a droplet of stress and back to safety. VERY careful systematic desensitisation and counter-conditioning is also beneficial. How this looks for each horse is unique and length of time this takes is also dependent on the individual. It is not enough to train an alternative behaviour over the top we need to address the horses underlying emotional state and recognise we can’t teach safety we can only support the conditions in which safety can grow. With time , patience and attunement we can also become a source of safety in the absence of horse friends .
