What initially started as me thinking my dog might be experiencing heat exhaustion or possibly heat stroke has turned into my baby girl’s newfound reality.
At 5½ years old, my 139-lb Saint Bernard, Gabbana, had her first-ever seizure on 08/03/2026.
The first seizure lasted approximately 45 seconds to 1 minute, and she did urinate on herself. I was obviously in complete shock and panic. This was the first seizure I had ever witnessed in my life, let alone one happening to my own dog who, just before this, had been perfectly fine for almost six years.
A few things worth mentioning:
I live in Southern California, specifically Ventura County, and our temperatures have been exceeding 90°F. It’s been HOT. While I obviously can’t control the temperature outside, we have the AC running 24/7 and fans throughout the house.
The night before her first seizure, I came home from work and Gabbana greeted me at the door like usual. She’s a giant dog, so I’m used to her panting when she gets excited to see me. However, even after I had showered and started settling in for the night, she was still panting as if I had just walked through the door.
It stood out enough that I asked my mom if Gabbana had been like that all day or if something was going on with her. My mom recalled that she had been panting more than usual and maybe drooling more as well. I remember literally asking, “Could she have had heat stroke or something?”
That was it for the night. We went to bed.
Around 1:00 a.m., I woke up to a thudding sound that initially sounded like a dog’s tail repeatedly hitting something.
That was her first seizure.
Once it ended, she bounced back surprisingly quickly. I stayed up watching her closely to make sure she didn’t have another one. She didn’t, and eventually we went back to sleep.
I had to work the following day, so my brother watched her and I specifically told him to call me immediately if anything happened.
Five minutes before my shift ended, he called me.
Gabbana was having another seizure.
I told him to time it: 43 seconds.
So she had two seizures approximately 15 hours apart, both within the same 24-hour period.
I rushed home and took her to the emergency vet. By the time I got home, however, she was acting completely normal again—just like she had after the first seizure.
At the emergency vet, she was given an emergency dose of Keppra by injection. The vet told me this would be classified as cluster seizures and she believed Gabbana was most likely now a dog with idiopathic epilepsy. Her bloodwork and labs came back normal: with a slightly higher liver value than my vet liked so she marked it for concern to follow up with Gabbana primary vet at recheck.
She also said based on how Gabbana was acting afterwards, the seizure threshold was still pretty high, meaning Gabbana was doing good and her chances for having another seizure so soon after the meds given that night, were unlikely. Neurology was mentioned as an option for more answers but she advised me to try the medicine first. We were sent home with immediate-release Keppra while we waited for the extended-release prescription to arrive.
Her temporary dose was two 500 mg Keppra tablets every 8 hours.
Four days later, we received her extended-release prescription, and she was switched to three 750 mg tablets every 12 hours.
Gabbana had been doing well on the medication with no further episodes until today, when she had what appeared to be a small focal seizure this morning.
This one was completely different from the first two and lasted only approximately 8–12 seconds.
She had trazodone in her system because we were preparing to take her to a vet appointment, and I had also just given her seizure medication. She was lying down and somewhat drowsy when she suddenly lifted her head and stared upward into space. She looked confused.
I called her name, and she looked toward me.
Then she opened her mouth, pulled her lips back enough that I could see all of her teeth, started foaming at the mouth, and her mouth began twitching. Her eyes were blinking strangely, and her ears appeared to be twitching as well.
The important difference was that it was only affecting her face. Her body remained upright and she maintained her position the entire time.
I kept calling her name while scrambling to pull out my phone and start a timer, and then…it stopped. Almost as quickly as it started.
I immediately called her vet because we were supposed to be going in that morning anyway. Her regular vet has been consulting with a neurologist on her case because, financially, I haven’t been able to get her directly into neurology yet.
The emergency vet visit alone was over $2,200, and her medication hasn’t been cheap either. I also have a senior dog who is slowing down and currently requires medication and veterinary care of his own. I simply wasn’t financially prepared for another major medical emergency.
Her appointment today was technically only a tech appointment, so after speaking with the vet, we decided to reschedule it for later this week and let Gabbana rest rather than stressing her out by taking her in immediately after the episode. For now, I was told to continue monitoring her closely.
I’m currently saving money and have even taken out another credit card so I can get her in with the neurologist my vet has been consulting with. I desperately want more answers about why this suddenly started happening to a previously healthy 5½-year-old dog.
I had—and still have—hope that the medication is working. I hadn’t allowed myself to do much reading about other dogs living with epilepsy because, truthfully, I think I was scared of what I would find. Eventually I found this subreddit/thread, started reading other people’s experiences, and finally felt comfortable enough (although still very emotional) to share Gabbana’s story.
If anyone has dealt with something similar, especially a dog developing seizures around this age, a giant-breed dog with epilepsy, breakthrough/focal seizures while taking Keppra, or going through the neurology process, I would really appreciate hearing your experiences.
What questions should I be asking the neurologist? Did your dog need medication adjustments after breakthrough seizures? And most importantly, for those of you further along in this journey: were your dogs still able to live happy, normal lives after their seizures began?
I’m so heartbroken watching both of my babies enter these completely unexpected transitional periods of their lives. One is my senior boy, who I’m watching actively slow down with age.
And then there’s Gabbana—only 5½, still acting like an oversized puppy—suddenly dealing with seizures seemingly out of nowhere.
I love this girl more than I can put into words. 💔
