Most seizures will stop within a few minutes, though the animal may be a little confused, dazed, or agitated for another few moments or few hours longer. Be aware, it is not uncommon for additional seizures to occur within the first 24 hours. Potential causes may be epilepsy, a toxin/poison, head trauma, heat stroke, a brain tumor, infection in the brain or spinal cord, or low blood sugar.
Focal Seizure (Petit Mal): Slight muscle tremors of individual or groups of muscles with full conscious awareness present. Some animals may show changes in personality, most commonly hiding and/or aggression.
Tonic Clonic (Grand Mal): convulsions, patient is incoherent, laying on its side, leg paddling. Mouth chattering, with foaming at the mouth. May urinate or defecate.
Transfer the animal to a veterinary facility immediately. During a seizure, be safe - avoid close contact that may risk bite.
Small animals: Place a thick blanket over the animal's entire body. Scoop up into your arms like a baby.
Larger dogs: Use a heavy blanket to cover its head (and help protect you). Have someone help carry the hind end.
