This is an odd one that Buster has pulled at least twice. Not go out into the driving rain to poop, pee. Finally goes outside. Pooped, Vomited, urinated, then staggered and fell over. Then he ran into the house. He did nearly the same thing thing two years ago, and he went to the vet where he proceeded to not allow his temperature to be taken and begged for treats. Vet had no clue so we went home. This time, less than 10 minutes later, he was jumping and doing spin tricks for food.Those would seem to require both strength and coordination. Now he seems more or less back to normal. I can't seem to find anything that would account for this kind of short term behavior. Some sort of seizure? Poisoning or illness wouldn't come on and disappear so fast.
