My puppy had a seizure. Is it due to low blood sugar from not eating?

Updated On September 23rd, 2025

Pet's info: Dog | Brussels Griffon | Male | 2 months and 26 days old | 1lb

My 11 week Brussel Griffon had a seizure today. He weighs a pound and 9 ounces. Unfortunately he ran out of his food yesterday. I was giving him a some Stella and chewy to hold him up till today. This morning I quickly realized that he wasn’t himself because he had no energy. That’s when he had the seizure. So I guess my question here is could’ve been because he had low blood pressure due to not eating enough yesterday?

Hello. The seizure may have been from a low blood glucose ( sugar ) level. Make sure Malone eats 3 good meals a day & if he skips a meal, have some Karo Syrup or Nutrical ( available at all pet stores ) on hand & give him 1/2 - 1 teaspoon to give him a sugar boost. If he continues to have seizures, even after eating well & on a regular basis, please have him evaluated for other causes of seizures. I hope he is doing better soon. Thanks for contacting Petco Pet Education Center, formerly Petcoach.

    Thanks for using Petco Pet Education Center, formerly Petcoach! This may be due to conditions such as idiopathic epilepsy (where no cause is found), low blood sugar, inflammatory brain disease, cancer, toxicity, among other possibilities. I recommend that you have him evaluated by a veterinarian as soon as possible to get more information and have a physical examination performed which may help narrow down the possible causes of this seizure. They will likely perform basic labwork to rule out the possibility of low blood sugar. Treatment for any of these conditions vary greatly and further advanced work up via a MRI will be needed to have a better idea or ultimately know exactly what is going on. Good luck! Hoping for a speedy recovery for Max!

    Epilepsy or a brain tumor are the top two things on the list. He should be on anti-seizure medication. It is not low blood sugar in a 5 year old dog unless he has a tumor on his pancreas. Please take him back to the vet and get him put on some medications to help control his seizures. https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951440

    I would recommend seeing your veterinarian right away. Even though Otis has a history of seizures, seizures could also be a sign of hypoglycemia (low blood sugar) and his insulin dose may need to be adjusted. If he has another seizure you should rub some Karo syrup on his gums and see a veterinarian immediately so his blood sugar can be checked.
