Introduction

Veterinarians often prescribe trazodone to help dogs with separation anxiety, noise phobias, and post-surgical recovery. But how much trazodone is safe for your dog?

What Is Trazodone?
Trazodone is a serotonin antagonist and reuptake inhibitor (SARI) commonly used in human medicine as an antidepressant and sleep aid. In veterinary medicine, it is prescribed off-label to manage anxiety and stress-related behaviors in dogs. It works by increasing serotonin levels in the brain, promoting a calming effect.

- Fear of loud noises (thunderstorms, fireworks)
- Vet visits and grooming anxiety
- Post-surgical recovery (to keep dogs calm and reduce excessive movement)
- Travel anxiety

Trazodone Dosage Guidelines
The typical trazodone dosage for dogs depends on their weight, medical condition, and individual response to the drug. Dosages usually fall within the range of 2.5 mg to 10 mg per pound (5-20 mg/kg), given every 8 to 24 hours as needed.
General Dosage Recommendations by Weight:
- Small dogs (10-20 lbs): 25-100 mg per dose
