Your dog lets itself out and back in

Your dog walks through without your help. Two hinged flaps sit in the opening, one behind the other.

No more checking the flap shut

You stop wondering if it latched. A strong magnetic closure pulls the flap shut after your dog passes through.

Frequently Asked Questions

verified +347 experts reviewed it as the best choice in 2026
Q1 Which size is right for my large dog?
Measure your dog's shoulder height and body width, then compare them with the flap, which is 279 x 416 mm (10.98 x 16.38 in) on size L. Pick the size where your dog passes through without squeezing.
Q2 What hole do I cut for the L size?
Cut 302 x 450 mm (11.89 x 17.72 in) for size L. Check your door is 30-50 mm (1.2-2.0 in) thick, measure the opening twice, then cut.
Q3 What cutout do I need for the other sizes?
S needs 185 x 275 mm (7.28 x 10.83 in), M needs 240 x 350 mm (9.45 x 13.78 in) and XL needs 370 x 635 mm (14.57 x 25.00 in). Measure twice before you cut.
Q4 Can I close it at night?
Yes. A metal back panel with a lock closes the door at night, so you can keep it shut when you want quiet nights.
Q5 Is it hard to install?
It mounts in your door with no wall tunnel. For size L you cut the opening to 302 x 450 mm (11.89 x 17.72 in), and you measure your door and the cutout twice before you cut.
Q6 My dog is nervous about flaps. What now?
Go slowly. Hold the flaps open with tape at first so your dog can see the way through, then let your dog set the pace.
