This is something new for us, Winston has never really chewed on his feet in the past, but when he came home from the groomers 2 weeks ago, he was chewing on his back feet. I assumed that it was from the clipping and maybe they went a bit short or something. Well, he's gotten a bath since then, has not been in any grass (fertilizer potential) and the pollen is just about gone in our area, so I can't explain why he's STILL chewing on his back feet. I have been washing them more, just the feet, with his regular non detergent shampoo and rinsing all the time, but I don't know if it could be something else that I am unaware of. We didn't change the cleaning solutions in our home or anything like that either. It's just his two back feet....any advice would be helpful!! Thank you in advance
