Seizures in dogs

Quick answer

A **generalised seizure** involves collapse, rigid or paddling limbs, drooling, and loss of awareness. **Keep your dog safe, time the episode, and call your vet afterward** — or immediately if a seizure lasts over five minutes, repeats in clusters, or follows toxin exposure. Tremors from fear or cold are different from true seizures.

Key takeaways

  • Dogs are usually unconscious during generalised seizures and do not feel pain in the way we might imagine. They may be confused, tired, or hungry after the episode — the post-ictal phase.
  • Yes — low blood sugar in toy breeds, toxins, and congenital conditions can cause seizures in puppies. Any seizure in a puppy needs prompt vet assessment.
  • A seizure lasting over five minutes, or seizures back-to-back without full recovery between them. This is an emergency — phone your vet or emergency clinic immediately.
