Questions & Answers

79 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.

Great concept, poor materials

As said, the concept itself is great and this will probably be the easiest dog door you'll ever install. That being said, the quality of materials is very much not on par with the price point. The screws will literally snap under light torque, the door sweep's adhesive is too weak to hold itself onto the door, and the lack of foresight to not include some sort of weather stripping to go between the sliding door and the dog door is kind of startling. Other than that, it's functional and much better for letting our dogs out on their terms than the magnetic screen we had previously.

Really a nice door for the price

This really is a nice door. We got it for our Jack Russell and our cats, and the old Rottie we just adopted goes right through. It's not wobbly, not cheaply made. If you are not handy, seek help before starting or you'll be really frustrated with the mounting and fitting. If you are putting it on a five foot slider instead of a six foot slider, and you are not a slim soul, you, as a human, might not be able to use your door (something that didn't occur to us). Hard to get the tape to work properly, and definitely not for winter egress in northern Pennsylvania, as it does leak air.

Easy to use

This pet door is really easy to use and install. I use it as a temporary door by just putting it in the track (no screws or anything) and it works well. My only gripe is that the weather stripping it came with is junk. You do not get enough to add to both sides and it does not stick! I put it on one side and within 2 hours it had come unstuck and fell off. So be prepared to supply your own weatherstripping. The door itself though is good quality and looks nice when installed. Cats and dog having it to go on the deck!

Perfect fit

Just what I was looking for. I was concerned about how tall it was at first, but it easily adjusts. I didn't have to install the hardware because we take it out at night. Easily removes and easy to put back in. Our standard poodle swoops in and out easily with the XL we purchased. However, she does scrape her back leg on the bottom when she goes out. I do wish the bottom part was a bit shorter to avoided that. Otherwise, I highly recommend.

Some install problems

The quality of the door is very good and buying an X-Large for my 50lb pitbull was the thing to do. However, installation was more difficult than planned. It took two people. We had a combo exterior and recessed door frame which made it very confusing on using the tpieces or not. We also noted that once the door was installed, there was not enough room for an average guy to walk through the rest of the doorway. Be sure to include the width of the door plus the width of a person walking through it to know if you’ll have enough space in your doorway to have pet door installed. Luckily we had two sliding glass door opening in our back wall leading outside so we could use the pet door on one opening and still have another door to walk through. We also had to buy a different lock to lock sliding door to pet door.

kitty door was a big hit

Handyman hired to install (I am just too short and not handy) - he said the instructions were very confusing and we just figured it out on our own to install. One machine screw was loose in the box but we didn't discover until we had already found a replacement. left the flap off and the cats used it right away as it was in their normal spot to go out onto the lanai. No need for the door - I can shut the glass slider at night since we put it on the track with the screen.

Super Product

We recently moved into a condo with a great patio for our cat. The Pet Door was easy to install and works great! We were leaving our sliding door open so Cheddar could have easy access to the patio that he loves, but wasting electricity at the same time. Cheddar learned to use it quickly and now we aren’t sending our air conditioning outside. We like the piece that comes with it to close it at night and in inclement weather. So far it’s been a great purchase and we are very happy with it.

Good but...........

The item itself is good but there are a few things that needs to be addressed by the manufacturer. One the extra large door is good for big dogs if you have a small dog also it doesn't work. The bottom is very difficult for them to get over coming in and out. The worst thing is the rubber they give to keep the air and bugs out. It simply doesn't work. Its cheap and it doesn't stay on. Constant air coming in and bugs .

I love this! It was super easy and fast to install and now my dogs get to enjoy the back deck while I'm at work. They still only go through it with the flap off, but it's very easy to take on and off. I'm hoping they will start using the flap soon. Best purchase so far!

Unable to deliver right item

Ordered this size, got the longer size that won't fit my sliding glass door. Chewy requested me to send this back before they send out a new one, so I did. Received the same WRONG size against. Chewy still won't send a replacement before they receive the original back, delaying this once again. Only recommended if you are willing to put up with returning this potentially multiple times.
