Response to a combined treatment program with clomipramine, behavioral, and environmental management of compulsive tail chasing in a German Shepherd.

A 15-month-old female German Shepherd dog showing compulsive tail chasing was treated with a treatment protocol of pharmacological therapy (using clomipramine) in conjunction with behavioral and environmental management. The responses to the treatment protocol were assessed once a week for 7 weeks in respects to behavioral conditions and the frequency of bouts and its duration. The behavior history including mother, father, and her littermates were also evaluated for the apparent diagnosis. The compulsive tail chasing of the patient dog was improved on the aspect of behavioral condition and gradually decreased in the frequency and duration of bouts. However, in the mid of treatment, the animal showed an aggressive behavior as a concurrent sign associated with compulsive tail chasing.
