CannaChews are hemp-based supplements designed to support the overall health of dogs. This supplement uses 99% broad spectrum cannabidiol (CBD). Possible benefits of CannaChews include treatment of digestive problems, nausea, anxiety, pain, inflammation, joints and mobility, epilepsy and seizures, aging and wellness, and skin diseases.
CBD supports dogs' nervous, gastrointestinal, and immune health through the endocannabinoid system, which is a group of specialized receptors in the brain, spine, peripheral nerves, blood vessels, and immune system.
The U.S. Food and Drug Administration (FDA) does not review non-drug health supplements (e.g., herbals, nutraceuticals, shampoos, and other supplements) for safety or effectiveness before they are sold to the public. Manufacturers of non-drug health supplements must ensure their supplements are safe and labeled accurately. The FDA requires that these non-pharmaceuticals contain a disclaimer that says, “This supplement is not intended to diagnose, treat, cure or prevent any disease.” Health Canada licenses “veterinary health supplements” after reviewing safety, efficacy, and manufacturing information provided by the manufacturer. These supplements are not tested by Health Canada.
Your veterinarian is the best source of information about the safety of non-drug health supplements in pets. Just because a supplement is natural does not mean it is safe. All medicines and medicinal plants are potentially toxic if used inappropriately or given at high doses. Supplements can also have side effects, like pharmaceuticals. Few supplements and herbs have been subjected to rigorous scientific trials to determine their efficacy.
Although the information in this handout may be helpful, it may also be incomplete and may not represent the full range of effects the supplement could have on your pet.
Studies show that CBD starts to take effect after 14 days of treatment at the dose recommended by veterinarians. In some cases, tolerance can develop, in which case your veterinarian may recommend an increase in the dose.
If you miss a dose, give it as soon as you remember. However, if it is almost time for the next scheduled dose, skip the missed dose and resume the regular dosing schedule. Do not give the pet two doses at once.
This supplement should stop working within 24 hours, although effects can be longer in pets with liver or kidney disease.
DO NOT USE CannaChews in:
USE WITH CAUTION in:
When used to control seizures, CBD containing products should be discontinued gradually, as a quick withdrawal can increase the risk of seizures.
Contact your veterinarian if your animal's condition does not improve or worsens despite this treatment.
There are no documented drug interactions for CannaChews; however, several drugs should be used with caution when given with CBD-containing products, including:
Be sure to tell your veterinarian about any medications (including vitamins, supplements or herbal therapies) that your pet is taking before starting any treatment.
If you suspect an overdose or an adverse reaction to the supplement/treatment, call your veterinary office immediately. If they are not available, follow their directions in contacting an emergency facility. Be prepared to provide information about the product and your pet's weight and symptoms. Report any adverse effects to the FDA or Health Canada.
