Well, it's yeast and bacteria. She's on clavomox and something else. We talked a bit about allergies and other stuff. Whoo hooo, potential for another allergy dog. How exciting.
She really just started chewing at her feet within the last month or so which seems to coincide with her increased crate time to deal with her housebreaking issues. He said it could be anxiety or boredome causing her to do it in her crate, and just a comforting thing for her to do when she's not in the crate but falling asleep (which is when I usually see it). So giving her the meds, putting some bitter apple on the feet, and giving her a frozen stuffed Kong during the day when she's crated so she has something to occupy her mind for a bit. Sooo, we'll see how it goes. Hopefully all will clear up in the next couple of weeks.
