I have the same issue. I have one big puppy and another big puppy friend who often stays over, sometimes for weeks at a time. And the two wrestle constantly. They have destroyed my old sofa.

After doing some research, my conclusion is that it’s probably best to buy something that has been made for a long time and has replaceable cushions with some durable fabric choices. I am not getting leather because I think it will just get destroyed too quickly.
