I know there was a discussion on what to do once the elbows get banged up, but is there a prevention out there to keep it from happening. Pitch's Elbows are a mess from the way he lays on our tile/hardwoods. Would like to prevent it if possible with Newt. I noticed a little bit of a rub mark already forming on him. Do they make elbow pads, if so, do they work? Any other ideas?
