E is for Epilepsy: How CBD Is Helping Dogs With Seizures (and What Your Vet Might Not Be Telling You)
Real science, trusted products, and the gentle support your dog might need.
If your dog has ever had a seizure, you know the fear.
The convulsions. The helplessness. The racing thoughts.
And the hardest part? Not knowing how to help.
For many pet parents, traditional anti-seizure medications like phenobarbital and potassium bromide can work—but come with major side effects like sedation or liver stress. That’s where CBD is starting to change the game.
We sat down with Dr. Tim Shu, veterinarian and founder of VetCBD, to talk about the science behind using cannabis for animals. If you're curious whether CBD can help dogs with seizures, this one's for you.
What Is Epilepsy in Dogs?
Epilepsy is one of the most common neurological conditions in dogs, affecting up to 1 in 20—especially in certain breeds like Border Collies, Beagles, and Labs. Many cases are idiopathic, meaning there’s no identifiable cause.
Traditional meds are often the first line of treatment. But when they don’t work—or cause more problems—many pet parents look for natural options that can offer gentle support without sedation. Enter: CBD.
Why CBD May Help: The Science
“The endocannabinoid system helps regulate brain activity, mood, and inflammation. Cannabinoids like CBD support that system—and that’s how they may help reduce seizures.”
— Dr. Tim Shu, VetCBD founder
CBD interacts with a vast network of receptors throughout your dog's brain and body. It’s been shown to:
Stabilize overactive neurons
Reduce inflammation
Support brain balance via the endocannabinoid system (ECS)
Dr. Shu explained that CBD is “promiscuous,” meaning it interacts with over 40 molecular targets, including:
5-HT1A receptors, involved in anxiety and mood regulation
GABA and glutamate systems, which affect nerve excitability
It’s this wide range of interaction that gives CBD its potential to help with seizures, anxiety, pain, inflammation, and appetite loss—a group Dr. Shu summarizes with the acronym P.A.I.N.S.:
Pain
Anxiety
Inflammation
Nausea and appetite loss
Seizures
Why We Recommend VetCBD
Not all pet CBD is created equal. In fact, many of the "CBD" products on Amazon don’t contain any actual CBD. They're just hemp seed oil—nutritious, but not medicinal.
“Hemp seed oil doesn’t help with seizures. You need cannabinoids like CBD, and those come from the flower—not the seed.”
— Dr. Shu
That’s why we trust and recommend VetCBD—founded by a veterinarian, tested for quality and safety, and backed by real-world results.
