Regarding how to choose the size for our parents,&Nbsp; The shop owner suggests that you can do a simple test here. First, find a piece of cardboard and use a ruler to mark the size of the inner door frame of the dog door. Then, cut a hole in the middle and let your beloved pet drill and try it out. If there is a slight squeeze, it can also be used. Once you get used to it, it will be easy!
