My Noel does this too. Well, she licks her leg not really her foot. Just watch though because I wasn't paying attention too much and then all of a sudden she had what I thought was an abcess but turned out to be a hot spot from the licking. The vet said that it could really be from anything, including just a habit. P.S. nothing was there to cause her to lick. Like you I checked and saw nothing, that's why I didn't pay attention. Never thought it would cause a hot spot though. Elaine |
