Size: Large for Door
Our dog door arrived quickly, the size was exactly as it was depicted, and the quality is great. We have 3 large dogs who had somehow managed to rip off the flaps of our old door repeatedly, but with the locking mechanism and metal door slide we will be able to protect the flaps from these crazy 3. Additionally, we live in Arizona where summer temps often exceed 100 degrees and the triple flap provides a great barrier between the outdoor elements and the indoor AC.

This thing is amazing. Not sure why I took so long to buy one. Its a must have item for your dogs that need to come and go without physical opening a door for them

Ordered 3, first was my mistake as I needed an exterior door fit. Second one was supposed to accommodate both my dogs only to discover that although it was for large animals my 100 pounder would've found beyond difficult to use. This one was great although it only has 2 flaps. Primary problem was my older girl (now deceased) with limited stability how great difficulty stepping over threshold and she needed the outer flap secured as she couldn't raise them both.

Installed the X-large yesterday. Instructions said to measure shoulder height of your dog then looking at the cut template it had a horizontal line for shoulder height. So I measured from the floor up on the door and put a mark at shoulder height, then placed the shoulder height line of the template on the mark and using a level I leveled the template out and taped it up. Drew a line all around the edge of the template, removed the template and once again checked for level. Then I cut a hole in my door. The instructions say to test fit the interior side of the doggy door (side with the flap). Little confusing because both sides have a flap. One has the outside cover flap and the insulating flap the other just has the cover flap. I guessed it meant the one with the insulating flap so that went inside. The hole I cut was about 1-1/2” larger all around than the door needed. I had to shim up the bottom with a 1” piece of scrap. So don’t trace around the included template, use the inside of the doggy door frame to draw your cut-out. After recovering from the excessive hole I cut I then drilled holes through the door using the pre-drilled holes in the doggy door frame. It’s imperative to drill these holes as straight as possible. After shoving the bolt thru if the bolt is at an angle you won’t get the other side on. Anyway, the kit comes with an assortment of mounting hardware. Drywall anchors and bolts, wood screws, cover caps… My door is 1-3/4” thick, not one of the included bolts was long enough to go thru the door. Picked up a handful of #8 nuts and bolts (3”) at Lowes and then after getting it all together I cut the excess off. I couldn’t use any of the included hardware. I’m giving it 3 stars for the confusing instructions and mostly having to drive up to Lowe's and back just to get 4 #8 X 3” screws and nuts. UPDATE: The seller must be reading these reviews and reached out to me apologizing for the confusion and offered to make things right. They even said they would be revamping the instructions to hopefully avoid such confusion in the future. I originally gave this product 3 stars because I believe it to be a decent product and looks and feels heavy duty. It was just the hassle I went thru to install it. But I'm upping my 3 star to a 4 star review because of the sellers consideration to future buyers and willingness to meet me halfway on the product.

It took a minute for my dogs to figure this out, but that is not the fault of the door itself. I have small dogs and they love it and I love the ease of having it. It was easy to install and looks great in my room.

This door is great! We live in a very cold environment and the door it is installed on faces the lake and NO wind or bad weather comes through! The door flaps are hefty,. but once our dog realized freedom was on the other side - he has no problem going through. Would recommend this dog door to anyone!~

Had to go w/ bigger window after our dog could no longer pull his hind legs up enough to use the original one. It is a great product. Even the cat uses it!

Missing parts so improvised. Been using for 4 months through winter and works good. Currently use for a 140+ pound dog and a 13 pound dog and they do great. I do like the triple layers of flap.
