Hello , I have an 12 year old male(non-nuetered) Shitzu. I came home today and was going to put it outside. He acted very strange. He seemed real dizzy and unsure of himself. He walked very slowly with big steps, as if he was feeling his way around. he went to shake his head(like they do when they are wet) and fell down, He did this twice. And now when he starts to shake his head he stops, because he is dizzy. In the past he has had some seizures, he will convulse and fall over. This usually lasts for about 10-15 seconds. After, he is tired but otherwise fine. He has never acted like he is now, ever before. The bottome line is that he is disoriented and dizzy. Thanks for your help.
