Thanks for your conference Amanda Stern. You gave no real advice just made someone feel like chit. Way to go. I have a Black Lab and also suffers from the same as you describe. I have never let them get to the point where the pussy and bleeding. It's natural for some big dogs Calussa hard to get those. It's just a question of what to do with them. For me, just ignore them. If I were to get as bad as you describe would clothes new bed or leave it to exercise more. If that fails I would consult my vet and see what he or she had to say. The Caluso are caused by pressure constant over the body part. Normally a joint or foot. Very common in larger dogs. As I said, trying to make exercise more and new bedding.
