Tail chasing in a dog: False dichotomy between behavioural and medical problems

Abstract A 6‐year‐old, male neutered, Border Terrier‒Pug crossbreed was referred with a 10‐month history of ‘constant chasing and traumatising of tail’. At the time of behaviour referral, there was a complex history of the problem, with initial investigations focusing on dermatological and neurological factors, leading to a presumptive diagnosis of a ‘behavioural problem’. Behavioural assessment revealed that the context appeared related to touch of the tail, suggesting that discomfort might be a contributing factor. Analgesia (meloxicam) resulted in significant improvements to the behaviour, with a partial amputation of the tail resolving the problem. This case highlights how the psychological impact of medical issues and discomfort need to be kept in mind throughout a behavioural evaluation. At a practical level, we recommend that general practitioners (and referral centres) create a habit of continuously reflecting on how discomfort may be involved in problem behaviour.
