One of my older dogs (a Sheltie) has been doing that for years. Back in the day, I took him to the vets, and while he never did it in front of the vet, he was checked out and I was told not to worry.
Since he's 13 and in good shape, I guess its not hurting him.
If it keeps happening, let your vet check her out, though, so you can rest in peace. |
