Not sure if this topic has been discussed before, but what type of doggy doors do owners have for their pet(s) to go in and out during the day? The most common ones I see are the adjustable height patio doggy doors, but those look kinda cheap (in terms of aesthetics/decor). Any suggestions on what people have or currently using that seems to work for them? (I have a 27 lb. frenchie.) Something that's safe and secure, provides good insulation, and somewhat pleasant to the eye?
