Trazodone, a commonly prescribed human antidepressant, is increasingly used by veterinarians to treat canine anxiety, stress, and behavioral issues. But how much is safe for your furry friend?

What Is Trazodone and Why Is It Prescribed for Dogs?
Trazodone is a serotonin antagonist and reuptake inhibitor (SARI), originally developed to treat depression and anxiety in humans. In veterinary medicine, it’s often used for:
- Separation anxiety
- Noise phobia (e.g., fireworks, thunderstorms)
- Post-operative calming
- Travel-related stress
- Veterinary visits or grooming anxiety
How It Works
Trazodone boosts serotonin levels in the brain, which helps promote a sense of calm and relaxation. It’s non-addictive, has mild sedative properties, and is generally well-tolerated by dogs.
100mg Trazodone for Dogs: Is It Safe?
100mg tablets of trazodone are often prescribed for medium to large dogs, but the actual dosage depends on your dog’s weight, age, health status, and specific condition. Giving the wrong amount can lead to side effects such as lethargy, gastrointestinal upset, or in rare cases, serotonin syndrome.
✅ Always consult your veterinarian before starting your dog on trazodone or adjusting the dose.
Trazodone Dosage Guidelines for Dogs
Here’s a general guideline based on mg per pound (or mg per kg). Most vets recommend 1.5 to 5 mg per pound, given every 8 to 24 hours depending on the situation.
