Trazodone for Dogs Dosage Chart By Weight Kg

Anxiety and behavioral issues in dogs are not just distressing for the animals themselves; they can also significantly impact the lives of their human companions. If your pet is dealing with these issues, trazodone may be an effective treatment option. But how much trazodone should you give to your dog? Let’s dive into the details and get a clear understanding of the trazodone dosage chart for dogs, based on weight in kilograms.

What is Trazodone?

Trazodone is a prescription medication primarily used to treat depression in humans. However, it has also found its use in veterinary medicine as a treatment for anxiety-related behaviors in dogs. It works by balancing serotonin levels in the dog’s brain, which helps to stabilize mood and reduce anxiety.

Trazodone Dosage for Dogs

The dosage of trazodone for dogs varies based on the size of the animal, the condition being treated, and the dog’s overall health status. The general recommendation is to begin with a low dose and increase gradually if necessary, under the supervision of a veterinarian.

Standard Dosage Guidelines

Trazodone is typically dosed at 1.7 to 9.5 milligrams per kilogram (mg/kg) of the dog’s body weight. It’s usually administered orally every 8 to 24 hours. For a starting dose, 2 to 3 mg/kg every 24 hours is often recommended.

Here’s a simplified trazodone dosage chart for dogs based on weight:

  • 10 kg dog: 20 to 30 mg
  • 20 kg dog: 40 to 60 mg
  • 30 kg dog: 60 to 90 mg
  • 40 kg dog: 80 to 120 mg

However, it’s important to remember that these are general guidelines. Your vet might adjust the dose based on your dog’s specific condition and response to the medication.

Possible Side Effects of Trazodone

While trazodone can be a powerful tool for managing anxiety-based behaviors in dogs, it’s important to be aware of possible side effects. These can include gastrointestinal upset, sedation, excitement, and panting. If you notice these or any other side effects, it’s important to notify your veterinarian immediately.

Other Factors to Consider

It’s essential to have regular check-ups with your vet when your dog is on trazodone. The vet can monitor your dog’s progress and adjust the dosage as necessary. Additionally, abruptly stopping the medication can lead to withdrawal symptoms, so it’s important to follow your vet’s instructions regarding tapering off the medication.


Trazodone can be a great help in managing anxiety and behavioral issues in dogs. However, the correct dosage is crucial to ensure its effectiveness and minimize potential side effects. Always consult your vet before starting any new medication for your dog. The trazodone dosage chart provided in this article offers a guideline, but your vet will provide the best advice based on your pet’s individual needs.
