Customer Question

My dog had what looked like a grand mall seizure this morning, he had vaccinations less than a week ago, can this be caused by dehydration, bad vaccine, or what?? My vet will not see animals on a Sunday.

This is Dr. KV. I'm sorry to hear your dog had a seizure this morning. Seizures are not caused by dehydration unless it is very severe. Vaccine reactions usually occur hours after the vaccine, so too much time has past for that to have caused the seizure today.

Can you tell me how old your dog is? Any other health issues going on right now?

Customer: replied 1 year ago.
Hi we believe he around 14 years old, he is a rescue we found 1.5 years ago. This is his second round of shots. He has never had any health problems at all until today. He looked like he was sleeping and having a bad dream because he was barking which he never does. Then I realized he was having a seizure

Ok, thank you for the additional information. Seizures are scary to witness. You will want to watch him closely over the next 48 hours, as many dogs will have a cluster of seizures within a short time frame. If he has more seizures today, taking him to a local emergency vet would be a good idea so they can give him medicine to stop the seizures and also they can check for the underlying cause. In older dogs there are many things that can cause seizures, so that would be a good way to find out more.

Do you have any idea other than vaccinations why he would suddenly have a seizure?
Expert:  Katie Volat replied 1 year ago.

The most likely things to cause seizures in older dogs are liver disease, brain disease, or possibly exposure to something toxic. A blood test will help rule out liver disease and toxin exposure.
