My 11 year old Border Collie has the right side of her face drooping really badly. Shes drooling all over herself and has little control in that area. This happened literally over night, and idk whats wrongwith her. At first i thought it was a stoke, but google says dogs dont get paralyzed when they have stokes. I think its something called Bell's Palsy, but im not sure. Can anyone enlighten me? Has anyone had this problem before? Please help out. Ive had her since ive been six, she cant go now. Is it serious?
