dogs and cbd oil

December 15, 2021 By admin Off

While it is legal to sell hemp-derived products containing less than 0.3 percent THC, until recently the American Veterinary Medical Association did not approve of veterinarians suggesting any cannabis products, including CBD, for patients. Even now, the law is unclear enough that many veterinarians fear repercussions if something went wrong due to their suggestion of CBD.

Choose broad-spectrum products, which include other cannabinoids and substances known as terpenes that are also in the cannabis plant. CBD seems to work best when it’s in conjunction with these rather than isolated. But avoid full-spectrum products that include THC.

Cancer: Cannabinoids are reported to induce cancer-cell death and prevent metastasis. In a Cornell University study of CBD, dogs, and cancer, researchers found CBD along with a standard chemotherapy drug reduced cancer-cell proliferation in vitro more than the chemotherapy drug alone. Anecdotal reports from veterinarians have claimed CBD shrunk cancer cells or put dogs into remission.

Seizures: Lots of anecdotal reports hail CBD’s success combatting seizures in dogs, but the single controlled study delivered moderate results. In this Colorado State University study, dogs given CBD for 12 weeks had 33 percent fewer seizures than those given a placebo, but it didn’t work for every dog. These researchers are now working on a larger trial using higher CBD doses. Note that THC has been reported to cause seizures, so it should never be included in any CBD product for seizure control. In addition, CBD’s effect on cytochrome P450 could interfere with prescribed anti-seizure drugs, so never use it without your veterinarian’s consent.

Research with dogs is still scarce, but there’s a huge body of research (about 23,000 published papers!) looking at CBD’s effect on laboratory animals and humans, with encouraging results for pain, especially arthritic pain, itchiness, anxiety, and cancer, all of which have at least one canine study as well. The results in dogs? It depends.

How to Choose CBD For Dogs?

Lady Amelthia, a Greyhound, was so petrified of thunderstorms she would destroy a crate to escape. “Holding her only made her claw to get away. A ThunderShirt reduced her from 100 to 90 on the anxiety scale,” recalls owner Jenn Boswell, director of the Alabama Greyhound Adoption Center. “Veterinary-prescribed trazodone took it down to a 50. Tried three drops of CBD oil and it went down to a 5.”

Topper, a 7-year-old Ibizan Hound, could hardly walk after being diagnosed with severe arthritic changes due to Valley fever. “The pain became so debilitating he had to be carried outside to eat, drink, or use the bathroom,” recalls owner Christy Moore. “He was on pain medication but it wasn’t working. A friend recommended CBD. Within three days he could walk on all four legs and I was crying tears of joy. It was the miracle we needed.”

Overall, the evidence is compelling that CBD can help at least some conditions. The endocannabinoid system is the largest system in the body, and the least explored. Every year brings new discoveries—and new claims. It’s the beginning of a brave new world of health, but as with any new path, expect some wrong turns, dead ends, and false hopes. CBD is not a miracle drug, but it may be the miracle your dog needs.

Aim for about 0.1 to 0.2 mg per kilogram of your dog’s weight, given twice daily by mouth. Work up gradually, but beware that more is not always better with CBD, as sometimes the response is biphasic, meaning that it doesn’t work if you give too little or too much.

Cannabinoids are substances including CBD and THC that mimic the endocannabinoid chemicals naturally produced in all vertebrates. Receptors for endocannabinoids are found throughout the body. The body’s endocannabinoids act as master regulators that signal other systems when to speed up or slow down, working to stabilize the body and return it to homeostasis. Cannabinoids from the cannabis plant affect these same receptors, each in slightly different ways. For example, THC causes a high, while CBD does not.

Unlike THC, which can cause toxicity and even death in dogs when given at prescribed human dosages, the worst CBD has been documented to do is cause diarrhea and changes in some liver enzyme values after several weeks. The main concern with CBD is that it inhibits a chemical in the body called cytochrome P450 that is responsible for metabolizing most drugs. If a drug’s efficacy depends on its metabolized product, CBD could render it less effective. If a drug’s safety depends on it being cleared from the body within a certain time frame, CBD could cause it to build up to toxic levels. Never give your dog CBD without your veterinarian’s knowledge if your dog is taking other drugs.

Success stories abound of dogs overcoming anxiety, slowing seizures, and even beating cancer due to cannabidiol (CBD), one of more than 100 cannabinoids found in cannabis plants. But how can one substance help so many unrelated problems? Or can it?

Many veterinarians are reluctant to suggest CBD, whether because they believe CBD is not yet sufficiently proven helpful or because they fear professional or legal repercussions. CBD products are not approved by the Food and Drug Administration for dogs, but neither are common supplements such as glucosamine or fish oil; nor the majority of human-approved prescription drugs routinely prescribed in veterinary practice.

While some veterinarians are hesitant to suggest CBD, almost all are eager to discuss it once you bring it up. Of course, some veterinarians are more versed in its pros and cons than others. The main concern is its possible interaction with prescribed drugs.

Other: There’s also evidence from laboratory animals that CBD is effective in promoting bone healing, fighting infection, treating inflammatory bowel disease, slowing degenerative myelopathy, quelling nausea, and relieving pain, but these have yet to be specifically examined in dogs.

Does It Work?

With hundreds of CBD products on the market, and little regulation of them, it’s not easy to know which is best. Look for a product with the National Animal Supplement Counsel (NASC) Seal of Quality Assurance, and one that has a third-party certificate of analysis that includes potency, lists all ingredients, and discloses the possible presence of heavy metals, mycotoxins, or pesticides. Avoid edible products formulated for human consumption, which often contain ingredients such as xylitol that are toxic to pets.

Itchiness: Two recent double-blind, placebo-controlled dog studies report CBD significantly reduces itchiness. An Australian study conducted by the company CannPal found their CBD product reduced itchiness, inflammation, and skin lesions by 51 percent after eight weeks of treatment. An American study conducted by the company ElleVet found their product, which combines CBD with another cannabinoid, CBDA, significantly reduced owners’ reports of itchiness.

Behavior: Anxiety, and especially noise reactivity, is a major reason dog owners seek help using CBD. But despite anecdotal reports of its effectiveness, no controlled study so far has shown it to be particularly effective. A study from the University of Western Australia may show promise for aggressive behavior. Shelter dogs with aggressive tendencies exhibited less aggression toward humans when tested after 15 days of CBD administration. In a study from the University of Kentucky, physiological measurements of anxiety in response to noise were not significantly different for CBD versus placebo, and were worse compared to trazodone (a drug commonly prescribed for anxiety). Note, however, that in this study the CBD was administered four to six hours before testing, which may have been too long a waiting period.

Arthritis: Several studies have looked at CBD’s effectiveness against arthritic pain, all with positive results. A Cornell University College of Veterinary Medicine study found dogs given CBD at a rate of 4.4 mg per pound twice daily for a month showed significant improvement in pain relief and quality of life. Lead investigator Joe Wakshlag, DVM, Ph.D., DACVN, said that some dogs were initially so decrepit that their owners considered euthanasia, but that after just days on CBD they were trotting around and even climbing stairs. A Baylor University study found similar improvement, adding that CBD worked better when delivered in a liposomal formulation.

Is It Harmful?

The safety and risks of using CBD for dogs have not yet been researched. The U.S. Food and Drug Administration has not approved CBD and has not issued a dosing chart. Therefore, we do not know what size dosage would be toxic. Any medication or supplement carries the risk of a reaction. It is always advisable, when giving your dog something new, to start out with small amounts and then closely monitor the effects. And always check with your veterinarian first.

The AKC’s Chief Veterinary Officer, Dr. Jerry Klein, explains what CBD oil is, what it does for dogs, and its safety concerns and potential side effects.

If you and your veterinarian decide that you should try CBD as a treatment for your dog, there are a few things to keep in mind when purchasing CBD oil. Not all oils are the same; you’ll want high-quality CBD oil to have a better chance of it working.

CBD, or cannabidiol, is a compound found in cannabis and hemp. Dr. Klein says it is essential to note that in most cases, CBD oil does not contain delta-9-tetrahydrocannabinol (THC), the compound that gives marijuana its psychoactive properties. In fact, most CBD products are derived from hemp and not from marijuana.

Risks of Using CBD Oil for Dogs.

Currently, there has been no formal study on how CBD affects dogs. What scientists do know is that cannabinoids interact with the endocannabinoid receptors located in the central and peripheral nervous systems, which help maintain balance in the body and keep it in a normal healthy state.

While there’s no scientific data on the side effects of CBD usage for dogs, there are potential side effects based on how CBD affects humans. To minimize any potential side effects, make sure you are following the proper dosage.

According to Dr. Klein, CBD is also used because of its anti-inflammatory properties, cardiac benefits, anti-nausea effects, appetite stimulation, anti-anxiety impact, and for possible anti-cancer benefits, although there’s no conclusive data on this use.

The AKC Canine Health Foundation (CHF) is sponsoring a study through the Colorado State University’s College of Veterinary Medicine and Biomedical Sciences to evaluate the use of CBD in treatment-resistant epileptic dogs. The CHF hopes that this will be the first study to gain scientific data on the use of CBD in dogs with this condition.

While there’s no definitive scientific data on using CBD to treat dogs, there’s anecdotal evidence from dog owners suggesting it can treat pain, especially neuropathic pain, as well as helping to control seizures.

As with any pet wellness trend, when it comes to CBD oil for dogs, there’s a lot of information floating around the internet, and it’s difficult to know what’s accurate and what’s exaggeration. Of course, you want to do what’s best for your pup, which leads to the question: What do I need to know about CBD oil for dogs?

Why are we hearing so much about CBD oil now? Dr. Klein points to the legalization of marijuana in many places, which has triggered interest in potential health benefits of marijuana-related products. “We are likely to see continued interest in CBD and an increase in research about its uses and efficacy in the coming years,” he says.
