I have a 3 year old Maltese, Harley. He has these strange epidsodes where he has these shaky like seizures? He starts shaking, curls up in a ball and gets lithargic. Sometimes he will throw his head back and his eyes will roll back (almost like a blind person would act). These episodes happen periodically. It may happen one day and not again for 6 months. Than sometimes 3 or 4 times in the same week. They last anywhere from 15 mins. to All Day. I just hold him until they go away. The Vet doesnt know what they are....he just gave me a mild sedative to give him when they happen that helps relax him. He also gets this weird gagging/hacking like cough. Almost like he is choking desperately...his body, his legs get all stiff...he makes this awful sound (like a Donkey) while this happens. This only last a few minutes...than all over and only happens maybe once a month.The first time both these episodes happened It scared the heck out of me!!. I thought he was dying. Now they both happen so often I just wait them out. But he seems to suffer so much while they are happening. What the heck!! Other than that he is perfectly healthy and happy! Any one with a Maltese who experiences anything like this?....if so, your input would be very appreciated!
