While both dog trainers and veterinary behaviorists address behavior, their roles and qualifications are very different. Dog training is unregulated, and trainers are not licensed to diagnose or treat medical or behavioral disorders. In contrast, veterinary behaviorists are licensed veterinarians with advanced training in clinical animal behavior medicine. They treat the root causes of behavior issues, which may involve medical conditions and neurochemical imbalances. Their care often includes diagnostics, behavior plans, and medication when appropriate.
