Buster was about that age when we got a doggie door. We took the flap off and put a dish towel on it, the dish towel was raised about half way up. We left that on for about a week, then we lowered the dish towel all the way. We left the dish towel on for another week, lowered all the way. Then we switched that out for a sheet protector, the things you put a piece of paper in. After a week of that, we put the flap back on. It about three or four weeks to get him to use it. I got that information from a web site. I would think with another dog he would use it. When we brought Maggie home, she followed Buster right out and learned from him.
