The Dog Mate Large Dog Door is the brown version of Dog Mate's two-way locking flap, listed at £42.80 and sitting eighth in this guide with 4.5 stars from 535 ratings. It is a plastic door with a brush-sealed, magnetically closed flap and a locking panel, sold for UPVC, metal, wooden doors and walls, self-lining to 50 mm.

The size wording in that listing does not line up. The title says Large, the Size field says L and the Dog Breed Size field says Large, but the Weight Capacity Maximum field says 20 Kilograms, and the Included Components field calls the product a "Dog Mate 2-Way Locking Flap Xl". The bullet's own measure is 630 mm (25 in) shoulder height, and the cut-out is 318 mm by 391 mm — those are the numbers worth buying on. Everything on this page comes from the Amazon listing, not from any test of ours.
