Last friday when i left for work my maltese was fine, upon returning home I found him behind a chair with both his front paws and chest soaking wet, I then picked him up and set him on the floor beside me and he started rolling like he was out of control and couldnt stand on his back legs. After taking him to a emer vet they said it looks like something to do with his brain, he has improved, he can now walk, but stumbles to the right, coughs and gags,isnt eating very well, and hasnt had a bowel movement since friday, not bubbly like normal, any ideas on what to do?
