Bare callous places on the dog from rubbing, chafing or lying on bare boards. Large dogs are very often so troubled. Glycerine or vaseline is used quite often, and keep treatment up for some time, either of which will soften and tend to remove these lumps. They do no harm but detract from the appearance of the dog. Eberhart's skin remedy will, in due time, fix them up, but should be well rubbed in, twice daily.
