Our border collie, Althea, has had grand mal seizures for the last year or so. She's 8 years old. Last night, she had 2 major seizures in a row. My daughter works as a vet assistant and was told that if she had another seizure before 3 weeks had passed, we should start giving her phenobarbitol (sp?). It had been 2 weeks since the last episode. They seem to be lasting longer with longer recovery times Anyone else with this experience and info to share? Input is greatly appreciated. Thanks.
