Products containing CBD are the latest wellness trend for people dealing with everything from anxiety, inflammation and sleep issues.

Now, products for pets are claiming to give animals a piece of relief.

The American Veterinary Medical Association has not endorsed using any CBD products and cautions pets owners against using it, but for pet owners like Lisa Bowman, the lack of official approval doesn't discount the changes she sees in her dog.

"When I take him on a car ride normally, he salivates like crazy and once I gave him the CBD oil and realized it worked, he doesn't do that at all anymore," Bowman said.

Bowman adopted her dog from a shelter after it had been surrendered by another family.

"I think just from the transition from going to a home to a shelter to us, there was just a lot of anxiety for him. He gets real nervous around other people," Bowman said.

At Smokey Mountain Feed and Pet Supply in Alcoa, sales of CBD treats and oil for pets have boomed in recent months.

Eric Grover, who works at the shop, says that natural alternative treatments for pets aren't anything new, but CBD's effectiveness has set it apart.

"Valerian root, St. John's Wort, chamomile mixtures, they come in tinctures also, and while I'm not going to say that they don't work, the CBD tends to work a lot better even with my own dogs," Grover said.

The CBD products Smokey Mountain Feed offers are from a company called Pet Releaf. A 7.5 ounce bag of treats runs around $16 and CBD oils in varying potencies range from $27 to $90.

In January, the AVMA published a guide for what veterinarians need to know about cannabis in its various forms. The publication says that hemp has not undergone the scientific review required to ensure safety for use in animal food and has not been approved as an ingredient.

The publication states that there is no FDA approval process for animal nutritional supplements. Animal products are only regulated as either animal drugs or animal feed ingredients.

The combination of these facts led the AVMA to caution pet owners against using any marijuana or hemp derivations in animals.

However in the marketplace, CBD products are gaining popularity due in large part to pet owners who swear by their effectiveness.

"Whether it's for animals or for humans, I think it's opening up," Grover said. "People are becoming more open to the idea of using this holistic, more natural approach to healing their ailments."
