French-Style Magnetic Panels: This doggy door for wall uses 2 center-opening panels and 3 magnet pairs that draw the panels back toward center after your dog passes, helping limit open gaps without a hanging flexible flap
Aluminum Wall System: The aluminum frame and telescoping 4–8 in tunnel give this doggie door for wall a finished passage through interior or exterior walls; confirm wall thickness before installation
Close Access Indoors: Cover the wall dog door from inside with the handled slide-in panel; locking pins hold the cover in position when you want to pause pet access overnight or while away
Measure Before Ordering: When comparing dog doors for large dogs, check chest width and torso height; the L opening is 13 3/5 in W × 18 1/2 in H, so body measurements—not breed name alone—should guide fit
Plan the Wall Cut: Install the in wall dog door only after confirming a 4–8 in wall thickness and a 13 5/8 in W × 18 7/10 in H cutout; check framing, wiring and plumbing before cutting
Everyday Pet Independence: A properly fitted large dog door creates a dedicated route for potty breaks, yard time and return trips, reducing how often someone must open a household door
