Have your friend check the hair around the muzzle of her yorkie to make sure hair has not been swallowed during eating. Lift the lips out and you'll be able to see if hair is attached and disappears into the mouth. If you pull on it, it should come up. I've had this happen and it caused similar symptoms. The other thing is the teeth could be loose in the the mouth. If it's none of these, a vet visit may be in order. |
