charlytuna Chevy Chase, DC 1/4/2015 9:35:16 AM I could have written this question myself, word for word with a few additions. Same breed, same age, same symptoms. He began retching so I ran him to the back door and let him out. He vomited yellow liquid, and when he went to straighten up he fell over backwards. Tried to get up and fell over again. Third attempt he got up and looked a bit wobbly but walked off and peed as usually. Came back inside and seems a bit shaken but ate a treat. He was shaking his head and also has been kind of grinding his teeth every now and then which he hasn't done before. I wonder if it is a common occurrence in min pins?Original question: Q. This morning when our 12-year-old Miniature Pinscher got up to go outside, he collapsed on his side. He tried getting up and fell over again. Then he walked out the door, but did not want to go down the steps to relieve himself. He came back and lay on his bed. About 45 minutes later, he was his old self. Could this be a sign of a stroke? Or is it something that just happened by chance?
