Last updated: 2026-06-09
Quick answer
A seizure can be frightening and may have many causes. Keep your dog away from stairs or sharp objects, time the episode, and seek urgent veterinary guidance, especially for repeated or prolonged seizures.
How to use this guide before a vet call
Start by checking the emergency signs below before you compare possible causes. Pet symptoms can look similar at home, so this guide is meant to help you decide how urgent the situation may be, what details to write down, and what to avoid while you are arranging veterinary advice.
For US pet owners, the safest next step is often a quick call to your regular veterinarian, an urgent care clinic, or an emergency animal hospital. Tell the clinic what you are seeing, how long it has been happening, and whether breathing, gum color, energy, appetite, bathroom habits, or possible toxin exposure have changed.

If any of these signs are present, contact an emergency veterinarian, the nearest emergency hospital, or a veterinary poison hotline now.

Is this dog symptom always an emergency?
Not always, but emergency signs such as trouble breathing, collapse, seizure, severe lethargy, blood, toxin exposure, or inability to urinate need immediate veterinary care.

Share when the symptom started, how often it happens, appetite and water intake, bathroom changes, medications, diet changes, possible toxin exposure, and photos or videos if they help.

You may monitor mild, short-lived changes when your pet is otherwise bright and comfortable, but call a vet if signs persist, worsen, or combine with other symptoms.
