My dog keeps having seizures, and the vet found nothing. What now?

Updated on September 23rd, 2025

My dog started having seizures 2 months ago. It has stopped ever since & just started back up this month. It's been going on for 2 days now! When we took him to the vet they told us they could not find anything wrong with him & to basically just let it be. This morning I was awakened from hearing my dog bumping against the wall & having a seizure. He was also howling while having it but I have never heard him howl before. Will my dog live? Is there anything we can do to stop the seizures?

I'm so sorry about your dog. I know this is a very scary time. There are multiple causes of seizures. I'm not sure how old your dog is, but in dogs under 5 years old who are completely normal in between seizure episodes, epilepsy is the primary cause of seizures. In older dogs it could be inflammation, a brain tumor, and infection or problems with the organs (particularly the liver). I always recommend blood work first to look for any problems there. If the blood work is normal, the next step is to evaluate the brain by doing an MRI. If blood work has not been done, I would highly recommend it. If problems are found in the blood work, then you should treat that. If everything is normal in the blood work, I would recommend starting seizure medication. Some dogs will have seizures very infrequently like your dog started out. Those dogs don't usually need medication. But when they become more frequent and are clustering (multiple in a 24 hours period) then I would definitely recommend medication at this point. There are multiple different seizure medications to choose from, so talk to your veterinarian about that. Many times the seizures will be manageable with medications, but it takes consistent medication multiple times per day and blood rechecks for the drug levels. Honestly, some dogs will be very difficult or impossible to control and will continue to have seizures despite being on multiple medications. So to answer your question, yes, there is something you can do to help your pet and based on the number of seizures he is now having, he needs to be put on medication. I hope this helps!

    Hello, thank you for using Petco Pet Education Center, formerly Petcoach. All seizures should be thoroughly investigated. We really need to know if there is some metabolic reason for the seizure, such as a liver problem, a toxic exposure, or some unexplained extra brain activity ( idiopathic epilepsy ). Once the blood work comes back, & hopefully nothing is unusual, then we evaluate how long & how bad the seizure was. One relatively mild seizure, we take a watch & wait approach. If the seizures become frequent, more that 1-2 per week, or are significant in nature, & last for minutes at a time, then medication will be required. Epilepsy is not all that unusual in dogs, & they can often be easily controlled with medication. If this was Patch's first seizure, you can wait to see if another ever occurs. It probably will, so be prepared to have things investigated so Patch can lead a normal life. Take care.

    I would suggest that you take him into a vet sooner rather than later. I assume Wrangler has had a few seizures over the last couple of weeks so this warrants treatment. To explain myself better, if seizures are a rare occurrence, for example once every 3-6 months, we normally just advice to monitor them and keep a diary with written the date and time they occurred , what was the dog doing and how long they lasted. If the frequency is once a month, then something needs to be done, It is difficult to pinpoint the cause by guessing. It could still be epilepsy, as it can occur in dogs from 1 year of age to more mature ones.(4-5 years old). It could also be a toxicity, liver disease, etc the list of differential diagnosis is long,
    If you book him in to see the vet, he is going to be checked over and probably just have a blood test to start with, so you are not looking at huge expenses but it would be a good starting point so that if Wrangler's liver is suffering for example, treatment could be started promptly and have a better outcome. I can see he is a very handsome boy from this picture ! Hope this helps.

My dog's first seizure: What to do and when to call the vet?
Seizures can be due to a few different causes. It can be due to certain diseases, organ failure, or imbalances in the blood. It can also be due to diseases, or tumors that primarily affect the brain. Without knowing the details of his condition, it's difficult to tell how severe this is. If Buddy is otherwise acting normal now, then this indicates that he is not experiencing a severe disease at this time. There are other conditions that may look similar to seizures, so it's possible that something else is causing the episodes that you are noticing. The most helpful thing to do is take a video of him when he is doing it and take that to the vet. In order to find the cause of this problem and get the most appropriate treatment, Buddy will need to see a vet. Unfortunately, there is nothing that can be done at home to prevent another episode. Preventing future seizures/problems is dependent upon getting an accurate diagnosis and treatment by a veterinarian. I hope that helps and all is well with Buddy.

My healthy dog had a seizure for the first time. What should I do?
I always recommend blood work to start with in any dog that started having seizures. There are a few things that could be diagnosed on blood work that could cause seizures, such as liver disease, kidney disease, electrolyte abnormalities, and infection. If the blood work is normal. Your vet will likely recommend that you continue to monitor Harley for seizure activity. Some dogs will have a seizure or two early in their life and never again. But some develop epilepsy that needs to start on medications. I generally wait to start medications until one of the following occur: -many seizures clustered together -seizures that are severe and cause bodily harm -the pet does not recover within 45 minutes after a seizure (should be tired, but otherwise normal) -seizures are occurring regularly (ie every month or two) Here is an article you may find helpful: https://www.petcoach.co/dog/condition/seizures-1/

Vet Q & A
My dog is having seizures. What are the causes and next steps?
Poor Chubbs. Seizures in dogs can be caused by a primary brain lesion, infectious disease, underlying liver problems (hepatic encephalopathy), metabolic imbalances (sodium), or in most cases they are idiopathic (no underlying cause). Chubbs needs baseline bloodwork to rule out most underlying causes of this. Once those are ruled out, then the vet will place Chubbs on anti-seizure medication to help manage his seizures and prevent permanent brain damage. It sounds like Chubbs needs to be regulated right away, especially if he is having more than 1 seizure a month and/or they are lasting for more than 2-3 minutes at a time. Best of luck controlling his seizure activity, I hope things work out for him.

My dog has seizures. How can I stop them or when should I see a vet?
Young dogs sometimes suffer from what we call idiopathic seizures (cause unknown) and older dogs that have never had a seizure before, can suffer from a brain tumor causing seizures. You should keep a diary of the seizures: situation that triggers it, time start, time ends, what the seizure looks like. If the seizure lasts more than 4-5 minutes your dog needs to see a vet right away, as this can cause hyperthermia and damage the brain. If you can you should take a little video of one such seizure to take with you to the vet and show him. Please make an appointment with your vet for an exam. He may want to put her on anti-seizure medication such as phenobarbital.

My dog has very long seizures. What can I do if I can't afford a vet?
These are extremely long seizures, i am surprised your dog is still alive with those very long seizures. seizures can be caused by many diseases but the vast majority of dogs with seizures is from an unknown reason. treatment for seizures is usually the same for all dogs, it's a medication that needs to be taken on a daily basis, this medication can only be prescribed by a vet.

Vet Q & A
My 13-year-old dog is having frequent seizures. What's wrong?
Poor Jackie! Unfortunately in an older dog who has no history of epilepsy, seizures usually mean something serious is going on. They can be caused by a primary brain lesion such as a tumour or they can be caused by the effects of toxin build up from organ failure, most often liver. They can be caused by other reasons such as high temperature or poisoning but the previous reasons are more likely. You need to get Jackie to a vet as seizures can damge the brain badly. The vet can examine her for clues as to a cause. Bloods can be useful to ascertain if it is organ failure. With a brain tumour clinical signs such as neurological signs can point to it, but mri tends to be the only full proof way to diagnose it. The vet will be able to administer meds to stop the seizuring then can decide the best treatment for her depending on the underlying cause. I will warn you that it is not going to be a case of curing her, but tryong to make her comfortable and manage symptoms. It is possible that her condition will be beyonf help and you may have to make the decision to put her to sleep. Good luck and give Jackie a cuddle from me.

My dog just had her first seizure. What should I do and what's next?
This will depend on the diagnosis. Seizures may be controlled with medications that your veterinarian can prescribe or dispense. A consultation with a veterinary neurologist may be recommended. In the meantime, begin a Seizure Log. For every event, record the time, duration, diet, medications, supplements and activity before and after. This may help your vet diagnose the underlying cause
