I have had short haired giant dogs all my life, and sometimes I wished they had had long fluffy hair to pad their elbows lol...... The one with the most callus problems was my bullmastiff boy, he also loved the cooler harder floor. All my others have been couch potatoes and not really had the problem.
The bag balm is good, I also saw and read about a new product just the other day, something that they said is for callus problems and would stimulate hair growth and keep the area smooth, and by keeping it smooth together with these vitamins or whatever it was in this new product, would help prevetent calluses.
I cant remember the name of the product though, I know it is in one of the newsletters I get from whoesale places, I will see if I can find it and post the name and brand though. If I dont remember totally wrong it was not an expensive product. Have no idea if it works any better than the good ol' bag balm though
