Is Melatonin Safe For Dogs?

First and foremost — before giving your dog any supplement, consult with your veterinarian. Your vet knows your dog’s health history and can make an informed recommendation on whether melatonin is safe for your dog. The safety and side effects of melatonin in dogs hasn’t been thoroughly studied, and the FDA has not approved it for use in dogs.

Side Effects

Don’t give melatonin to pregnant dogs and puppies under 12 weeks old.

There are several risk factors for melatonin in humans, but these are unknown for dogs. People with liver, kidney, or heart disease should use extreme caution when using melatonin, so you may want to use caution if your dog has any of these conditions.

Dosing

How much melatonin can you give a dog? It depends on your dog’s weight, health conditions, and what it’s being used for, so you should always get your veterinarian’s recommendation for dosing.

A general rule of thumb for melatonin dosage (up to 3x daily) for dogs is:

  • Less than 10 lbs: 1 mg
  • 10-25 lbs: 1.5 mg
  • 26-100 lbs: 3 mg
  • Over100 lbs: 3-6 mg
