How do you know if a dog has epilepsy?

Watching your dog go through an episode that seems out of their control is one of the scariest things a pet owner can experience. Epilepsy in dogs is more common than many realize, especially in certain breeds, but recognizing the signs early can make a huge difference in managing it. It’s not just about seizures—there are subtler clues that something might be going on with your pup’s neurological health.​

Seizures themselves are the most obvious sign, but they can look different from dog to dog. Some dogs might collapse, stiffen up, and paddle their legs as if running in place. Others could drool excessively, chomp their jaws, or lose control of their bladder or bowels during an episode. These can last from a few seconds to a couple of minutes, and afterward, your dog might seem disoriented, tired, or even clingy. They might wander aimlessly, bump into furniture, or refuse food for a while. These post-seizure phases, called the “post-ictal period,” are just as telling as the seizure itself.​

Not all seizures mean epilepsy, though. Epilepsy refers to recurring seizures with no clear underlying cause—like a brain tumor, infection, or toxin exposure. So if your dog has a single seizure, it might not be epilepsy. But if they have more than one, especially spaced a few weeks apart, it’s time to talk to your vet. Puppies and young adult dogs are more likely to develop idiopathic epilepsy (the kind with no known cause), while seizures in older dogs often point to other health issues that need investigation.​

There are also warning signs that a seizure is coming, sometimes called an “aura.” Your dog might act restless, hide in a corner, whine, or seek extra attention right before an episode. Some owners notice their pup licking their lips excessively or staring into space. Catching these cues can help you get your dog to a safe place—away from stairs, sharp objects, or water—before the seizure starts, which can prevent injuries.​

If you suspect epilepsy, keeping a detailed record can help your vet make a diagnosis. Note the date and time of each episode, how long it lasted, what your dog was doing before it started, and any unusual behaviors after. Did they eat something new that day? Were they stressed? These details matter. Your vet will probably recommend tests like blood work or an MRI to rule out other causes, as treating epilepsy is different from treating seizures caused by another condition.​

It’s important to remember that epilepsy isn’t a death sentence. With the right management—often medication—many dogs with epilepsy live long, happy lives. But ignoring the signs can lead to more frequent or severe seizures, which can be dangerous. Also, in some regions, there are guidelines around managing dogs with certain health conditions, so working closely with your vet ensures you’re following best practices for your pet’s care.​

Knowing what to look for helps you act fast, which is key when it comes to your dog’s health. Those little changes in behavior, the strange episodes, the post-seizure tiredness—they’re all pieces of the puzzle. Trust your gut: if something feels off, it’s worth getting checked out. Your dog can’t tell you when they’re in trouble, so being their advocate is one of the most important things you can do.
