Combining cannabis and melatonin treatment with a rehabilitation program improved symptoms in a dog with compulsive disorder: A case report.

Abstract

Compulsive disorder in dogs (CD) is characterized by constant and time-consuming repetition of behaviors, emancipated from the environment, that definitely compromise their everyday life activities. Here, we documented the efficacy of a novel approach to counteract the negative symptoms of CD in a 5-year-old mongrel dog, previously found to be resistant to the conventional antidepressant. The patient underwent an integrated and interdisciplinary approach, based on the cannabis and melatonin co-administration, together with a tailored 5-month-lasting behavioral program. Observational findings showed a lower rate of compulsive episodes and better management of the dog as well, when compared to the previous paroxetine treatment. We followed him for an additional four months of therapy, and the owners reported easier management of the dog, as reduction of abnormal behaviors to a level acceptable to the owners. Overall, our data so far collected in the CD dog may allow us to test more deeply the feasibility and safety of such an off-label approach, at both preclinical and clinical levels.
