Cooper has been licking incessantly at his paws in the last few days. The last time this happened the vet told me to put him in warm water with Aveeno Skin Relief Oatmeal in it. It worked great...after 7 days he was much better. This time, though, he didn't even want to get in the water and couldn't get comfortable while he was in there. Seemed to make it worse. Any new suggestions?
