At Colorado State University, the College of Veterinary Medicine and Biomedical Sciences is conducting two clinical trials with Cannabis CBD – one involving treatment of arthritis, and the other epilepsy in dogs.

For now, CBD advocates for dogs are spreading the word at ground level. Cannabis at human strengths can be toxic for dogs, so firms are making dog chews, oils and topical creams using cannabis extract.

Similar companies include Treatibles, which sells a hemp oil “for animals of all kinds”, and Pet Releaf, whose hemp dog treats look like fancy vegan snack-food.

The compound Cannabidiol (CBD) was discovered by studies to reduce inflammation and combat seizures. Veterinary groups are cautious but a mounting number of dog owners say the Cannabis is easing their animals’ anxiety and chronic pain.

Cinnamon, a portly Beagle cross from Kansas City, Missouri, takes PetReleaf’s hemp oil daily for her bad hips. Her owner Joyce Lattimer claims that after one dose:

She hopped right down from her chair when I called her to go outside. usually I have to call several times and start pushing her off.

She came over just to say hi and lick me on the leg. I almost cried, it’s been so long since she’s done that.
