Golden Retriever male showing aggression toward owner at home

Abstract

Abstract A Golden Retriever male was exhibiting owner-directed aggression (growling, snarling and baring teeth) and occasional avoidance behaviour of the male owner within the home environment. Blood tests and X-rays prior to assessment were unremarkable in addition to an unsuccessful analgesic trial. Extensive information gathering was undertaken during the assessment and in the months that followed. Potential motivating factors identified, including gastro-intestinal discomfort, frustration, physical stress (lack of appetite and lack of rest) and defensive behaviour, proved challenging to isolate. A multi-modal approach to behaviour modification was applied, including further exploration of the dog’s health to rule out undiagnosed pain. giardiasis antigen was identified during a faecal screen and treated, resulting in an improved appetite. Potential gait abnormalities were observed leading to examination by a hydro therapist and registered physiotherapist, both of whom could not identify any concern. Following the owner reporting a potential pain response to the dog’s hind-foot being touched, the referring veterinarian opted to prescribe a second analgesic trial using a different medication. Aggressive incidents ceased to occur while the dog was on pain relief, and the aggressive behaviour returned once the trial was completed. This led to the continued use of analgesia and a further cessation of aggressive behaviour, despite no formal health diagnosis being made by the referring veterinarian to date.
