my ali has them. they put her on phenobarbital but I took her off. they wasn’t helping. but I can tell about 2 days b4 she has one and if she takes med’s it’s not severe. it kills me to watch I happen. unfortunately she was dropped on her head when she was a puppy and me and doc thinks that’s wht is causing them. she’s a tea cup chihuahua at that. I do know that the pill they give for fleas is WAY BAD on dogs with seizures
