I have a pit that I've used catching hogs for yrs. He'll be 8 yrs old July first. He broke out of my back yard so i had to put him on a chain till i could fix it... 3 days on the chain and he started acting really funny. Drooling out his right side and his head is cocked sideways to the right. He tries to run but he almost falls like his right leg don't work. I originally thought he might have something wrong with his ear that was throwing off his equilibrium. But today i noticed when he opens his mouth his right upper lip don't move... i sure hope it's not a stroke but it sure resembles one.
