A 2019 paper published in Clinical Therapeutics lends some evidential weight to these claims—at least for its use in humans. When CBD ointment was used for three months on participants with psoriasis, atopic dermatitis, and scars, their skin conditions showed significant signs of improvement.
CBD interacts with the body through the endocannabinoid system. This system has receptors throughout most of the body’s major organs and can affect all kinds of internal processes.
So, why might you want to target cannabinoid receptors in a dog’s skin? There are four main reasons for delivering CBD via the skin (but don’t feel limited by these—other reasons are just as good too!)
Treating dryness, rashes, and skin issues
In the same way, topical application of CBD is able to zone-in on problem skin far more effectively than oral ingestion, because it will work directly on-site rather than entering the bloodstream (which means losing some CBD as it’s processed by a dog’s metabolism.)
In order to avoid the formation of negative associations with CBD, it can help to familiarize anxious dogs with CBD oil before you attempt to orally administer it. The easiest way to do this is by placing a small amount of oil on your hand and letting your pup investigate. If that goes well, then try stroking your dog with the oil still applied.
If you’ve googled CBD oil recently, you’ll know there are numerous ways to introduce your dog to the benefits of this cannabis derivative.
It’s also worth pointing out that CBD oil is, well, an oil. It’s therefore a natural option for moisturizing and conditioning your dog’s fur and skin. Unlike other moisturizing oils, however, CBD gets its calming and soothing effect without the need for any additives.
Like seizures, the term “cancer” is an umbrella term that refers to an extremely diverse set of specific diseases, each with their own set of beneficial treatments.
Anecdotal reports do exist of dogs becoming somewhat sleepy or sedate if they receive extremely large doses of CBD, but those effects appear to resolve on their own with time.
Studies on using CBD for dogs with arthritis or seizures generally use a dose between 2-8 mg/kg, with most papers erring on the lower side of that estimate (roughly 1-2 milligrams per pound of body weight), twice daily.
Unlike CBD, THC ingestion can cause serious problems for your pet.
But because CBD is not psychoactive, it is unlikely that CBD has the ability to directly treat canine anxiety in the way that Prozac and other medications do. The use of CBD for anxiety in dogs, as with most conditions, requires substantially more research.
