Sudden seizures, paralysis, or inability to walk can be frightening. Some neurological symptoms arise from problems in the brain or spinal cord; others come from toxins, metabolic disease, trauma, or low blood sugar. Owners cannot reliably diagnose the cause by watching the symptoms alone.
Go to an emergency veterinarian for these signs
- A seizure lasting about five minutes or longer: Ongoing seizure activity is an emergency.
- More than one seizure in 24 hours, or poor recovery between episodes: Cluster seizures can be dangerous.
- Sudden paralysis, inability to stand, or severe back or neck pain: Some spinal cord problems need rapid evaluation.
- Collapse, unconsciousness, severe confusion, or suspected poisoning: These can reflect life-threatening disorders beyond the nervous system.
What to do during a seizure
Start a timer. Move furniture and other pets away, keep the room quiet, and protect the dog from stairs or sharp edges without restraining the body. Do not put your hand or an object in its mouth; a seizing dog cannot swallow its tongue. If safe, record a brief video for the veterinarian. Once the dog is recovering, keep your distance if it seems confused or disoriented.
What other signs mean
Head tilt, circling, wobbling, abnormal eye movements, or new weakness may have several causes, including vestibular disease and neurologic injury. Even when not an immediate emergency, new symptoms deserve timely veterinary evaluation. Do not assume a wobbling dog is simply getting old.
How a veterinarian investigates
A neurologic examination helps localize the problem. The vet may order blood tests to assess glucose, electrolytes, and organ function, or recommend imaging and referral. Not every dog with a single brief seizure has epilepsy; diagnosis requires considering other possible causes.
What to avoid at home
Do not give human anti-seizure medicine, sedatives, or pain relievers without guidance. Do not force a dog with weakness to walk. If your dog takes prescribed anti-seizure medicines, ask the clinic about missed doses and have a plan for recurring events.
