What is Veterinary Behavior Medicine?
A veterinary behaviorist is a licensed veterinarian with advanced training in diagnosing and treating complex behavioral issues in animals—essentially the psychiatrists of the veterinary world. These specialists complete a rigorous residency program and earn board certification through the American College of Veterinary Behaviorists (ACVB).
Combining medical expertise with evidence-based behavior modification techniques, they address a wide range of concerns, including anxiety, aggression, compulsive disorders, and house soiling, working with animals from household pets like dogs and cats to exotic species such as wolves and tigers. What sets them apart is their ability to assess how underlying medical conditions may influence behavior, ensuring that treatment plans support both physical and emotional well-being for lasting results.
Veterinary Behaviorist vs. Trainer
Veterinary behaviorists are veterinary doctors uniquely qualified to diagnose and treat behavioral disorders linked to medical conditions. They offer comprehensive treatment plans that include 3 key components: a behavioral medical diagnosis and medications; a behavior modification and training plan; as well as safety and environmental management techniques.
To provide the most well-rounded care, our doctors often collaborate with certified positive reinforcement trainers. Trainers specialize in behavior modification and skill-building, helping to implement the treatment plan effectively and compassionately. Together, we create a supportive, integrated approach tailored to each pet’s unique needs.

- When training hasn’t worked, or behaviors are hard to manage
- Behaviors affecting well-being or causing tension at home
- Trouble with vet visits or grooming
- Safety risks to people or other animals
- Preventive reasons—before adopting a new pet, moving, or having a baby

What To Expect
Behavioral concerns and psychiatric treatment require ongoing management, and we provide continued care to ensure long-term improvements. If the first visit doesn’t feel very “therapeutic” that’s okay! The goal of your initial appointment is for your provider to gather information and build rapport and trust so they can formulate a treatment plan to best support you and your pet.

Initial Behavior Evaluation:
- 90 minute in-person consultation
- Thorough assessment of behavior and medical factors
- Personalized treatment plan development
Follow-Up Care
- Telemedicine rechecks
- In-person rechecks
- Scheduled every 4-6 weeks until behavior is stable
- Sedated exam if needed for the extremely fearful pets
Behavioral concerns require ongoing management, and we provide continued care to ensure long-term improvements.
Behavioral Medications & Their Role
Medications may be recommended as part of a comprehensive treatment plan, particularly when daily stressors are unavoidable. While psychopharmacologic therapies do not "cure" behavioral disorders, they can help lower baseline anxiety, improve coping mechanisms, and enhance learning during behavior modification therapy.
