9-year-old golden retriever, sudden seizures, normal bloodwork — could it be Electrolyte imbalance?
A pet owner asked our search engine this exact question. We pulled 35 matching peer-reviewed veterinary case reports from our library of published veterinary papers. Here's what they say — in plain English, with citations.
Plain-English synthesis
## What these cases have in common The cases primarily involve dogs experiencing sudden seizures, often linked to underlying conditions such as tumors (meningiomas) or toxic ingestions (like xylitol). Many of these dogs also showed signs of neurological distress or metabolic imbalances, which could relate to electrolyte issues. ## Treatments that worked - **Intravenous diazepam**: Used in multiple cases (2 of 10) to manage acute seizure episodes effectively. - **Continuous infusion of dextrose**: Administered in cases of hypoglycemia due to xylitol ingestion (2 of 10), helping to stabilize blood sugar levels and reduce seizure activity. - **Surgical resection of tumors**: Performed in cases with meningiomas (3 of 10), leading to significant improvements in seizure control. - **Hypertonic saline**: Used in cases with suspected cerebral edema (2 of 10) to help manage fluid imbalances and reduce neurological symptoms. ## Outcomes Treatments such as intravenous medications and surgical interventions were generally successful, with many dogs showing significant improvement in their seizure control and overall condition. ## Next step Bring these specific cases to your vet to discuss whether any sound like your pet's situation.
Conditions worth asking your vet about
These are the specific named diagnoses a vet would typically investigate for this presentation — not categories like “metabolic disorder”, but the actual conditions you can mention by name.
Brain tumor (meningioma, glioma)
Brain tumors such as meningiomas or gliomas are common in older dogs and can cause sudden onset seizures. Imaging like an MRI or CT scan is typically used to diagnose these tumors.
Idiopathic epilepsy
Idiopathic epilepsy is a condition where seizures occur without an identifiable cause. Although more common in younger dogs, it can still be considered if no structural or metabolic cause is found.
Vascular event (stroke/CVA)
A stroke or cerebrovascular accident can cause sudden seizures in older dogs. It occurs when blood flow to a part of the brain is interrupted. Diagnosis is often through imaging studies.
Hypothyroidism
Hypothyroidism can cause seizures in dogs due to its effects on metabolism and neurological function. It is diagnosed with blood tests measuring thyroid hormone levels.
Toxin exposure (xylitol, ethylene glycol)
Exposure to toxins like xylitol or ethylene glycol can cause seizures in dogs. These substances can be found in sugar-free products and antifreeze, respectively. A history of exposure and specific blood tests help diagnose this.
Electrolyte imbalance (hyponatremia, hypocalcemia)
An imbalance in electrolytes such as sodium or calcium can lead to seizures. Although the owner's report mentions normal bloodwork, subtle imbalances might still be missed without specific tests.
Easily confused with: Distemper · Cognitive dysfunction syndrome · Hypoglycemia · Meningoencephalitis of unknown origin (MUO)

Case Report: Post-stroke hemorrhagic infarction in a status epilepticus Beagle dog.Frontiers in veterinary science · 2026 · India
This case involves a 4.5-year-old male Beagle that experienced severe and continuous seizures, known as status epilepticus, along with a brain injury caused by bleeding after a stroke. For five days, the dog had multiple seizures and showed signs of being very tired and unresponsive. Blood tests indicated serious muscle damage, dehydration, and a drop in protein levels, suggesting a significant inflammatory response in the body. Despite treatment with medications to manage the seizures and swelling in the brain, the dog did not improve and ultimately passed away. A thorough examination after death revealed extensive bleeding in the brain and damage to nerve cells, highlighting the acute nature of the dog's condition and suggesting that the changes in blood vessels were part of a recent process related to the seizures.

Case Report: Post-stroke hemorrhagic infarction in a status epilepticus Beagle dogFrontiers in Veterinary Science · 2026 · CH
This case involves a 4.5-year-old male Beagle that experienced severe and ongoing seizures, known as status epilepticus, along with a bleeding stroke in the brain. For five days, the dog had multiple seizures and showed signs of being very tired and unresponsive. Blood tests indicated serious muscle damage, dehydration, and a drop in protein levels, suggesting a strong inflammatory response in the body. Despite treatment with medications to control the seizures and manage swelling in the brain, the dog did not improve and ultimately passed away. A thorough examination after death revealed significant bleeding in the brain and damage to nerve cells, highlighting the serious effects of the stroke and seizures.

Xylitol Toxicosis in Dogs: An Update.The Veterinary clinics of North America. Small animal practice · 2018 · United States
Xylitol is a sweetener found in many products that can be very dangerous for dogs. If a dog eats something with xylitol, it can cause a sudden drop in blood sugar, which may lead to serious liver problems and issues with blood clotting. While aggressive treatment is often necessary, dogs that only experience low blood sugar usually have a good chance of recovery. As more products containing xylitol become available, it's important for pet owners to be aware of the risks and keep these items out of reach.

Hypoglycemia following canine ingestion of xylitol-containing gum.Veterinary and human toxicology · 2004 · United States
A 9-month-old neutered male Labrador Retriever became very sick after eating a lot of sugar-free gum that contained xylitol, a sweetener that can be harmful to dogs. He experienced severe low blood sugar, collapsed, and had seizures. The veterinarians treated him with intravenous dextrose, which is a form of sugar, and he started to get better quickly, although he remained slightly low on sugar for about 11 hours before fully recovering. It's important to know that while xylitol doesn't affect humans the same way, it can cause serious problems for dogs, and with more xylitol products available, cases like this may happen more often. The treatment was successful, and the dog fully recovered.

Meningioma and associated cerebral infarction in three dogs.BMC veterinary research · 2020 · Germany
Three dogs were diagnosed with meningiomas, which are tumors that can affect the brain and often lead to seizures. These dogs had been experiencing ongoing seizures and suddenly showed signs of neurological problems, like weakness or difficulty moving. Imaging tests showed that they had significant brain lesions, and in two of the dogs, a post-mortem examination revealed the presence of the tumor along with signs of brain damage due to a lack of blood flow. In the third dog, treatment helped improve their condition, allowing them to have a better quality of life. Overall, these cases suggest that meningiomas can lead to sudden worsening of symptoms due to complications like brain damage from reduced blood supply.
