Dog Seizures: Causes, When to Worry, and When to Seek Care
Seizures in dogs can be frightening to witness and often happen suddenly. They may involve shaking, loss of consciousness, muscle stiffness, or unusual behaviors. While some seizures are brief and may resolve on their own, others can indicate a serious underlying condition that requires immediate attention.
Understanding what a seizure looks like and what might be causing it can help you respond quickly and appropriately.
Common Causes of Seizures in Dogs
Seizures can occur for a variety of reasons, ranging from primary neurologic conditions to systemic illness. Common causes include:
- Idiopathic epilepsy (common in younger dogs)
- Toxin exposure (certain foods, plants, medications, chemicals)
- Head trauma
- Brain tumors or neurologic disease
- Liver disease (such as hepatic encephalopathy)
- Kidney disease
- Low blood sugar (hypoglycemia), especially in small or young dogs
- Infections affecting the brain or nervous system
In some cases, the exact cause may not be immediately identified.
When Should You Be Concerned?
Any seizure should be taken seriously, but certain situations require urgent or emergency care.
You should seek care immediately if your dog:
- Is experiencing their first seizure
- Has a seizure lasting more than 1–2 minutes
- Has multiple seizures in a short period (cluster seizures)
- Does not fully recover between seizures
- Appears disoriented, weak, or unresponsive afterward
- Has known exposure to toxins
- Is a puppy, senior dog, or has underlying health conditions
If your dog is actively seizing, keep them safe from injury and seek veterinary care as soon as possible.
This Requires Immediate Emergency Care
A seizure can indicate a serious underlying condition and can quickly become life-threatening. This is not something AnimALL Mobile Veterinary Service is able to treat.
If your pet is showing signs of a life-threatening emergency, please go directly to the nearest emergency veterinary hospital rather than waiting for a mobile appointment.
