Owner-directed aggression can pose serious challenges to the dog–human relationship. In this case, a Golden Retriever male displayed aggression and avoidance toward his male owner at home. Initial veterinary examinations, including blood tests, X-rays, and a first analgesic trial, yielded no clear explanation.
Through extensive behavioral assessment, several possible contributing factors were identified, including gastro-intestinal discomfort, frustration, lack of rest, and defensive reactions. A faecal screen revealed giardiasis, which was treated and improved the dog’s appetite. Despite this, aggression persisted, leading to further investigation of physical discomfort.
Although physiotherapy and hydrotherapy assessments did not confirm abnormalities, the owner noted signs of a pain response when the dog’s hind foot was touched. A second analgesic trial with a different medication was prescribed. During this treatment, aggressive incidents ceased, only to return once the medication was withdrawn, strongly indicating pain as a trigger for aggression.
This case underscores the importance of considering underlying medical issues in cases of aggression. It demonstrates how behavior modification and veterinary collaboration can provide a comprehensive, multi-modal approach to managing complex behavior problems in dogs.
