Limitations to weigh

Measure your dog's shoulder height and widest point; the flap top should sit at least an inch or two above the shoulder, and the step-over should be low enough for seniors and short legs.
Any flap big enough for your dog can let in wildlife, other animals and, rarely, people; lock the closing panel at night and when you are away.
Door and wall installs mean cutting; check for wiring and studs in walls, metal or glass in doors, and rental rules before you start.
