PetSafe's Extreme Weather Energy Efficient Aluminium Pet Door sits at number two in our best dog doors guide at £104.99, with a 4.5 rating from 6,157 reviews. It is a white aluminium-framed door with a three-flap system, an insulated centre flap, a magnetic seal and a slide-in closing panel, and the listing gives a flap opening of 26 cm x 41 cm inside an outer frame of 32 cm x 50 cm.

The number that does not hold still on this listing is the weight. The title and the size fields say Large (L), the bullet says the door is made for pets up to 45 kg, and the catalogue field Weight Capacity Maximum says 100 kg — two figures for the same door, more than double apart. Everything on this page is taken from the Amazon listing for this product, not from any testing by us.

What buyers actually say

Quoted from customer reviews on Amazon

Verified purchase

“English storm easily gets through, but you can always use plastic cover the close it.Our door needed an adaptor as it was thinner than the flap (cheap and you can buy it from petsafe). Silent.We love it overall.”

“Quick and easy to install, even I managed. Big enough for our Alaskan Malamute and German Shep (plus a lil gremlin pooch). Seems to be a magnet for "dog dust" so make sure you're wiping it every few days, makes life easier.”
