Cannabidiol (CBD) has gained popularity as a potential alternative or complementary treatment for dogs with seizures, especially for those who do not respond well to traditional medications. Unlike conventional anti-seizure drugs such as phenobarbital or potassium bromide—which can be effective but may carry side effects like lethargy, liver damage, or increased thirst—CBD is often praised for its more natural profile and relatively mild side effects.
Preliminary research and anecdotal reports suggest CBD may help reduce the frequency and severity of seizures in some dogs, likely due to its interaction with the endocannabinoid system. However, while early results are promising, CBD is not yet a replacement for veterinary-prescribed medications. It may be best used as a supplement under a vet's guidance, particularly since dosing, purity, and drug interactions need careful monitoring. Ultimately, the choice between CBD and traditional treatments—or a combination of both—should be made in collaboration with a veterinarian familiar with the dog’s specific health needs
