Questions & Answers

81 Customer Questions

Can this be added to sliding door side

What constitutes a ‘recessed’ door?
Answer by ChewyDec 20, 2017
A recessed frame is flush with or barely visible in the interior or exterior wall so you can't see the track the door slides into.

Is the glass insulated for cold weather?
Answer by ChewyAug 01, 2017
These panels feature a heavy-duty aluminum construction and shatter-resistant, tempered safety glass.

How do I install it and make sure my current sliding door will lock. Also would we still be able to use that door to access the back yard?
Answer by ChewyJun 12, 2020
This door includes a locking kit which will take the place of your sliding glass door's existing lock. It also comes with a hard panel that can be slid in front of the flap to close off the dog door when desired, and a heavy-duty aluminum construction and shatter-resistant, tempered safety glass.

Awesome, life changing

I picked up a new Toy Poodle a couple weeks ago and the breeder had the coolest set up. She had finished a back porch into an extra room, for a kennel. This room was complete with a little doggy door and a beautiful fenced in play area. She kept the pups in their kennels at night and opened them during the day. All day long they, even the little puppies, ran in and out. I needed to do this, but I had a patio door! After searching the internet, i found several options. This option, from Chewy, looked like the best value. It is fantastic. My son helped me install it, but I could have done it myself. My new little 8 week old puppy, ran out the door, so all the others followed. Training done. Love, love, love this doggy door system.

It hopefully will work

I bought this as my husky feels the need to have our sliding glass door open 24/7. No, is not an answer for her. We had a magnetic screen door, and it worked great in the summer. However, as it gets colder, our dog is freezing me out!I got this, hoping it would be the perfect fit. Wrong! There were tons of gaps, one of the screws kept stripping, it was loose front to back, and the bottom T bar didn't fit. I made a lot of adjustments, including a ton of weather stripping. For the price, I was not happy with how much I had to do outside adjustments.

great door, somewhat finicky install

Once I figured it out, install wasn't too bad. Tiny gap next to sliding door on one part but very minimal. I worry a bit about it being possible to pry open in middle with crowbar or something though. Also - get the smallest size you can. I got medium and my ex boyfriend was able to shimmy himself through there and break into my house. I wish I had a vid for proof and because it would prob be funny to see him slug his way through. I can fit through as a medium/small lady but I def didn't expect that!

Works great

Easy installation. However I didn't do the lock kit. If placed on the screen door railing I can open, close, and lock slider when needed. My pet learned quickly how to use and we haven't had any issues. Stays in place. I also love how it comes with the flap cover to close off access.

Incredibly easy to install

Love this pet door! It was so easy to install I didn't even need the directions. Matches my sliding glass door perfectly. Well made, too! Only took me about 5 hours in a span of 3 days to train my dog to use the door but she's a pro now!

This worked out perfect for me

Teddy enjoys being outside so much so this has been great for him. It was easy to install and with a little additional weather stripping it will be suitable for Minnesota weather

Doggy door for sliding patio door

This was the best purchase I have made. My puppy can go in and out without having to wait on me to let him out!

Great for Big dogs, not for small dogs or cats

I have an American Bulldog ( 100pds ), a Chihuahua & 2 cats. The door is amazing for my Bulldog, at first she was scared of the flap. Then got used to it after a day or so. But the cats haven't been able to go through, not only cause the flap is a bit heavy but their timid also. For small dogs, I think its a bit difficult for them to come back into the house because of the white piece at the bottom. My Chihuahua has to climb over it and its a bit difficult for him. just an fyi, overall great product. rain or shine.

Awesome door to love the backyard life

Overall I’m very happy with this. Super easy to install, super easy for my cats to use, it took one try to push them thru it for them to figure out how the magnet flap worked. The only improvement I would make to it is better insulation. I think thick insulation strips for both side should be added because there are definitely gaps. The fault could be my sliding door’s but all I know is the black rubber border they provide doesn’t do much especially the glue wears out. But easy fix. I bought insulation strips to keep all the gaps sealed and keep bugs out
