A New Study Analyzes Long-Term Administration of CBD In Dogs

A joint study by Hill’s Pet Nutrition and Colorado State University investigated the effects of long-term CBD consumption on dogs. Three groups of dogs were given different CBD doses for 36 weeks to determine how well they tolerated it. Most dogs experienced no health issues and the ones that did have taken the highest dosage on a daily basis.

In this study, 18 healthy Beagles were divided into three groups. Each group received 0, 5, or 10 mg of CBD per kilogram of body weight each day for 36 weeks. The reported results said that none of the dogs experienced serious health impacts. The only effects reported were loose stools and one elevated liver enzyme in some dogs taking the highest CBD dosage.

Breonna Kusick, neurology clinical trials manager at Colorado State University said,

“This study was important to show that dogs can tolerate doses generally much higher than what most of these brands are marketing towards. However, it’s important to note that these are all very healthy dogs, and the higher doses may not necessarily be as well-tolerated in dogs with any sort of illnesses or on any additional medications.”

She went on to suggest that pet supplement brands do two things. One is staying on top of current literature. The second is for brands to share their knowledge and educate pet owners on various signs of health problems to watch for if giving dogs CBD. The symptoms include diarrhea, vomiting, fatigue, and decreased appetite.

Currently, the government allows CBD in pet supplements, but it has not approved adding CBD to animal feed. The reason is that there is a belief more research is needed on the potential effects on humans after consuming animal products made with or from animals that fed on CBD-infused animal feed. Hemp seed products are Generally Recognized as Safe (GRAS) by FDA, but hemp seed only contains trace amounts of various cannabinoids, including CBD.

The CBD industry continues to lobby the Food and Drug Administration for more regulation of CBD and other industrial hemp products. Established regulations would increase product safety and enable CBD brands to grow their businesses nationwide within the regulatory boundaries. The coalition of 33 hemp industry groups calling upon Congress for regulation of CBD and other industrial hemp plant products will hopefully trigger action.
