Thanks collyk. My cousin did check it out with the vet, more than once. There is a term used to describe the condition (which I can't think of just now) but as you say, not totally abnormal, especially if the dog wasn't trained not to do it when young.
My cousin claims that she couldn't catch the little duffer doing it often enough or consistently enough to train her not to do it. The dog is getting old now, so I guess it hasn't done her much harm. And I don't mind when the dog comes to visit, because she doesn't mess up my lawn.
Oh yeah, and to Teenah. Sorry about that, hee hee.
