Having had a L A R G E dog, I would say that if the dog left a claw print in the first armrest, he's likely to do it in the next armrest. You might be better off finding a good piece of heavier stronger leather and velcro'ing it on top of the armrest, replacing as needed. There are all sorts of sources for good leather online these days, all sorts of colors and grades so it can look professionally done.
It followed me home. That's my story and I'm sticking to it.
