How Much CBD for Dogs?
A common starting dose is about 1 to 2mg of CBD per 10 pounds of body weight, given once or twice a day, starting at the low end and adjusting slowly. There is no FDA-established dose for dogs, so weight-based guidance and your veterinarian’s input are the best references, and a THC-free product made for pets is essential.
Because the FDA has not set an official dose, most guidance comes from veterinary studies and product labels, which cluster around 1 to 2mg of CBD per 10 pounds of body weight. A 2018 Cornell study on arthritic dogs used about 2mg per kilogram twice daily, toward the higher end of that range. Smaller dogs need proportionally less and large breeds more, and factors like why you are using it and your dog’s sensitivity shift the number. The safest approach is to begin at the low end, around 1mg per 10 pounds, and increase gradually over a week or two while watching how your dog responds.
Practical dosing is easier with a pet-formulated CBD oil, which lists milligrams per dropper so you can measure by weight. Give it consistently, ideally at the same times each day, since CBD is thought to work best with steady use. Do not use human products that may contain THC, xylitol, or heavy sugar, all of which are dangerous for dogs, and choose a THC-free pet CBD instead. Always confirm dosing with your veterinarian, especially if your dog takes other medication, since CBD can affect how the liver processes drugs. For the safety rundown, see is CBD safe for dogs.
