3. Choosing the Right Size for My Dog
For an X large dog, I made sure the flap opening was tall and wide enough for my dog to pass through without crouching too much. I looked for a door that could comfortably fit large breeds like Great Danes, German Shepherds, or Labradors. A bigger opening made a huge difference in my dog’s comfort.

Since the door would be installed in my sliding glass door, I wanted good insulation. I checked for features like magnetic closures, draft seals, and weather stripping. These details helped reduce air leaks and made the door more suitable for both hot and cold weather.
