Really effective dog door for larger dogs. Labrador and Bernese in and out like Yo-yo’s. Wind / weather resistant too.

This is another automatic dog door that has thousands of reviews and this is actually an ‘Amazon Bestseller’.

First things first, it’s a cheap electronic dog door (at the time of writing – it’s less than £30) and is available in 2 different sizes: Medium and Small. That ultimately means it’s not suitable for larger dogs.

It’s a “no frills” automatic dog door. It’s budget friendly and has some fantastic reviews and it performs well, is water proof, silent and lightweight.

It’s not as beautiful in its design as other dog doors but that’s not always important to purchasers – we’ll let you be the judge.



Here’s a highlight from some of the thousands of reviews available on Amazon:

After studying reviews for dog doors I opted for this dog door in a size medium for my 25lb Tibetan Terrier. My partner fit the dog door and it took a couple of hours but apart from initially taping the frame to the dog door upside down – doh – it was quite straight forward. As pictured the screws are too long and need to be cut down to size but our TT was using the flap confidently within 24 hours and loves her freedom. We ‘lock’ the dog door at night so she cannot go out and bark and she can easily tell when it’s blocked.

I’ve had a competitor’s make of dog door fitted for year’s now but my new puppy would not use it because it had two moving parts (the semi transparent flap and a outside section which also moved) and the noise of them moving scared her. Reviewers of this dog door stated that it was quieter and only the semi transparent flap swung open.
So I decided to give this one ago and it’s great because from the moment it was fitted she used it with no encouragement from us.
It is much better quality than other types of dog flaps we have fitted, much quieter and draft proof.
Really recommend this one.

My dog now has their own living room at the basement. He learned how to use the sliding door immediately. Though our dog and us live in Spain, it was so much cheaper Amazon from the UK that the Spanish Amazon. The sliding door was too tall for our window but we had it cut, no problem about it. We are very happy and satisfied.

It fits into door no trouble and the dog took one look at it and started using. Had to remove the mag strip at the bottom though as too heavy for the dog.
