Yesterday while we were playing I noticed a little raw spot behind Deuce's ear. There was a lot of hair missing and the area was all red. In the middle there was a little spot where the skin was broken. I think he might have been scratching with his foot and got a little carried away. However, I didn't see it happen so I am only guessing that is what it is. If it is, what should I do to get him to stop scratching? He doesn't have any fleas or tics, and he is inside all the time, except for maybe short play periods outside. I have had his collar off for the past few days, b/c he always scratches at it. So, I guess it isn't the collar b/c it didn't show up until after I took it off, but that also made his ear and neck easier to scratch. Any advice?
