I have two puppies, one (Freckles) is happy to use the doggy door to go outside and do her business. The other (Bruno) will use the door when Freckles or I hold him open for him, otherwise he just sits there staring at the door.
I have tried luring him out with treats but he just won't go through unless its held open. He won't even come through when it's half open.
I'm out of ideas. Until now I was holding the door up permanently with string, but it's getting too cold and defeats the purpose of the doggy door. Can anyone help?
