I dont have a pic, But I will try to explain. My bulldog Zeus has a small but growning calluse.I think that is what it is . It is black and the size of a dime. Looks exactly like what you would see on a very large dog that sleeps outside on his elbows. He is so perfect everwhere that I really want this thing off him ,its only on his one heel .So far I have tried ..
1. Vasoline
2. Rugs everywhere he sleeps.
3. foot cream ,with vitamins .
4. Doo grow for hair regrowth (loaded with vitamins and lanolin(this helped a little.
5. Medicated body powder.
6. washed it with warm water with epsom salt in it.

I have it under control .Just a minor thing I want gone completely and doesnt seem to be going away, any suggestions would be great . thank you.
