Introduction

Behavioral disorders in dogs—especially separation anxiety—can be difficult to manage without medical support. While training plays a major role, some dogs require medication to stabilize their emotional response.

One of the most established medications in veterinary behavioral medicine is clomipramine, a tricyclic antidepressant (TCA) specifically approved for use in dogs with separation anxiety.

It is often prescribed when:

• Anxiety is chronic
• Behavior is severe
• Training alone is not enough
