Mine will lick any body part that has a boo-boo. Foot, shin, arm, shave nick on face. My accident prone DH hates it because Katie goes over board and will try to "flea bite" off a scab–eewwww.
She grooms her 'brother' Tyler in the same way. For years he had a little skin tag on his jaw, after Katie found it, it was gone in no time. I forgot all about it until my vet was doing a hand-rub body check and kept rubbing his face and jaw and checking her notes. Then said it was peculiar that the tag was gone and that that didn't usually happen. I laughed and said Katie had worried it to death:eek: We stopped Kate every time we saw her, but you know that Basenji thought pattern and tunnel vision. She waited until we were at work or not watching. No bleeding, no scab, no tag. Vet Laurie just laughed and said "That's our Kate. She not only did it cheaper than I could have, but with less trauma to Ty. :D"
