. I have a yellow border collie about 4 1/2 yrs old and she’s always been a paw licker always trying to get het to stop but wasn’t huge issue but now constantly biting them to the point of blood. It’s the only part of her that she’s biting and no fleas ang other dog seems fine. I don’t know how to get her to stop. She loves to cuddle and be pet but for some reason she looses it when you touch her paws and she’s always been that way. Anyone know I can stop this?
