I am ashamed to say that I let my daschihuahua's back paw develop an in-grown paw nail. It had circled around and grown into her paw pad. I cut the nail off when I found it, and then pulled it from her paw pad. I then proceeded to apply a castor oil pack (directions elsewhere on this site) and banished the infection overnight. Nice going, earth clinic - you helped me help my dog. No vet visit necessary.
