could I have a min pin that is about 5 lbs. She will be fine and all of a sudden she will go in circles and then fall down like she is unconscience. After a few seconds she will slowly get up and then be fine again. What is causing this?
This could be a seizure or a metabolic disease such as a liver shunt. I recommend that you see a vet about this. A diagnosis should be made b/c this sounds serious. Good luck, vetcare
