Does CBD really help seizures?

Dog seizures are very distressing. Traditional treatments for seizures can have serious side effects and don’t work in roughly 30% of cases.1 Cannabidiol (CBD) is a natural and safe anticonvulsant that has proven effective in early research and may help alleviate seizures in our canine companions.


CBD for Dog Seizures


The American Kennel Club is currently sponsoring a major research study regarding use of CBD in dogs for treatment-resistant epilepsy. That said, most animal studies on CBD and seizures are performed on rats, where CBD has been shown to combat seizures, reduce seizure severity, and enhance other seizure medications.2-5


Patient reports and early human trials support the use of CBD for treatment-resistant epilepsy.6-8 In a recent double-blind study by the New England Journal of Medicine, 10-20 milligram doses of CBD were administered to children with treatment-resistant epilepsy, and significant reductions in seizures were recorded compared to placebo.9 The Food and Drug Administration approved CBD as a treatment for this form of epilepsy in 2018.


It is unclear how CBD acts to produce anticonvulsant effects. However, CBD is safe for dogs, and the canine endocannabinoid system is similar to ours.


Why is My Dog Having Seizures?


The most common cause of seizures in dogs is idiopathic epilepsy, or primary epilepsy. This genetic condition causes generalized seizures (unconscious with whole body convulsions). Secondary epilepsy is caused by structural issues in the brain and manifests partial seizures (conscious with erratic seizure symptoms). Our dogs can also have seizures in reaction to many factors in their bodies and environments. It is vital to consult a licensed veterinarian if your dog experiences seizures.


When our best friend suffers, we suffer. Seizure treatment can be challenging, but CBD may help. Discuss CBD with your veterinarian to determine the best course of treatment.
