I have a dog that paws at the screen door when he wants to go out, does anyone know of a way to protect the bottom part of the screen on the door? We tried to put up a grate, but we were not able to get the door shut. When we are at the camper I just set the grate in front of it which helps somewhat, but he has gotten so big, we had to take out his crate and his new crate will not fit in the 5th wheel unless I take out more of the furniture so that means he will be loose inside while we are not there, and I am afraid he will paw it. Any suggestions? (and no I will not leave him at home)
