(WKBN) – CBD products, produced from the cannabis plant, are popping up just about everywhere and in some pet foods.

The products come as treats, pills and oils, but critics say most people don’t know exactly what they’re buying because CBD isn’t regulated.

Experts say pet CBD is one of the fastest-growing areas of the market. They say it can help animals with anxiety, osteoarthritis and pain.

Some veterinarians say there needs to be more research. According to the American Kennel Club, there hasn’t been a formal study looking at how CBD affects dogs but anecdotal evidence suggests it is helpful.

The AKC Canine Health Foundation (CHF) is sponsoring a study through Colorado State University’s College of Veterinary Medicine and Biomedical Sciences. It will evaluate the use of CBD in treatment-resistant epileptic dogs.

Possible side effects include: (Source: American Kennel Club)

  • Dry mouth: Research has shown that CBD can decrease the production of saliva. For dogs, this would manifest as an increased thirst.
  • Lowered blood pressure: High doses of CBD have been known to cause a temporary drop in blood pressure. Even though the drop is small, it might create a brief feeling of light-headedness.
  • Drowsiness: Dog owners have used CBD to treat anxiety. The calming effect of CBD can also cause slight drowsiness, especially when using higher doses.
