I have a 4mo. old male pup, that as been doing find until yesterday. Three days before this he had cherry eye. I massage the closed eye, and it went back in. He acted a little funny the next day( walking slow ). He has been eating and drinking water fine, no vomiting, stool is soft/soild, but the cherry eye returned and he would not stand. I have to help him up and outside he will walk, but slow, will not walk in the house. Can you help?
