Rank #8 in Best Dog Doors 2026: 10 Ranked, and What 'Large' Really Means
Dog Mate Large Dog Door, Brown
Price and rating as shown on Amazon when we collected them. Both change.
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.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Easy to fit with the instructions. You need a jigsaw for the hole and a spare pair of hands is helpful for final fitting as the door inserts are a wee bit fiddly.”
Verified purchase“This was a replacement and as it was to go in a brown door it looks great! Just need the puppy to learn how to use it, maybe a bigger 'window' would help?”
