Elbow Butter All Natural Balm Conditions Your Dog's Elbow Calluses Elbow calluses are uncomfortable for your dog, as the thick tissue inhibits movement. Elbow Butter is packed full of rich, uber-moisturizers that melt into your dog's elbow callus easing the tightness of the elbow callus and conditioning to help prevent cracking. What Causes Elbow Calluses? Your dog's overprotective ulna bone tries to protect the bony part of the elbow that hits the ground when your dog hits the ground hard next to their thick, plush bed. With every landing the ulna tells the skin to get thicker and thicker. Enough hard landings can cause the callus to become cracked, bloody, infected or ulcerated. Our large/giant breed dogs (not fat shaming) put more force/weight into their landing, which multiplies the effects. Plus, bigger dogs may be hotter and want to relax on a hard, cool surface such as; concrete, tile, the deck or patio or good old dirt. It's a vicious callus creating cycle!
