Ever since my dog, Lily, got groomed at the beginning of this month she has been licking her left front paw. I have examined it as thoroughly as I can and can find nothing amiss with it and cannot figure out why she has suddenly started doing this. It does look like it is starting to get a little red around the bottom of the pads from her licking. What can/should I do to stop this? She is 6 yrs. old and has never shown any other type of neurotic behavior. Do they ever do this just because they are bored? Thanks for any advice.
