Large Smart Dog Door For Sale (2024 Update)

Good study quality at a great price..just wish the flap was a little bit longer other than that I am super happy with the purchase…jajoh-4659

Lifechanging! We were slaves to our pets and now laugh at the German Shepard who jumps in and out constantly. Our cats took a minute to overcome the heavy flap but are now using regularly. Even our blind chihuahua who is very timid has even become accustomed to it.Amanda

This is a great dog door. I bought it to replace a well used older PetSafe medium door. It took a little longer to install since my door already had a previous door. Mostly it required more trim and fitment time to install, if you have a good grinding tool or hand file set it will really help. The door slides easily in place without binding. It does flex just enough that if someone wanted to enter the house from outside with it closed they could open it. But it is not meant as a security device just to prevent kids and animals from getting out which it does well. It looks great installed, very flush to the door, seals out the drafts really well. All of my dogs including my small pug size mixed breed has no problems going in and out the door. I still need to seal the outside but I'm glad I bought this door.YaheeTech

Being a senior widow im on my own. I installed this myself in a wood door. I thought whats the worst that could happen..buy a new door. Got er in just fine actually was easynancy

We have not installed it in the door yet…but just looking at it, it looks sturdy and indestructible, which is good, because my dog literally eats and tears the doors with the flexible plastic. He's a monster. This should do the trick. Well put together and hard plastic tri-flex door flap. Best price I can find for these is here!!Kim

I have 7 dogs of varying sizes who use this door constantly. The only fault I find is that the rubber gaskets between the slats in the door wear out . Everything else lasts a very long time. I tweaked it by putting piano hinges between the slats and that has extended its use a lot. If I could buy just that part the door would last practically forever! Even with my over-sized pack!HappyKat

Having two doggy doors has always been a problem. The prior doors were made of plastic and with our weather changing all the time, the would break apart quickly but not with these new Metal doors. And the flap is even made better. Couldn't be more pleased!!priddyclover

When purchasing they say aluminum frame. The don't tell you the security door is made of very thin PLASTIC. Another example of cheaply made American crap by a greedy, deceptive corporation. What ever happened to quality?2justftw

I recently added a little screened in outdoor room for my cats and dogs to use for a little outdoor time. This pet door works perfectly. The dogs and the cats have no problems using it. It’s big enough for the dogs and easy enough for the cats to use too. I especially like the added inner flap that helps keep the hot outdoor air out. The slide in insert is great too because I like to close it at night to keep anything from possibly getting in the house. This is not the first time I’ve used a Petsafe door and it won’t be the last. Great productJohnnypat

Awesome quality product! Bought 6 for our kennel and are great! Lil pricey but you get what you pay for. Bonus that you can buy replacement flaps if needed.davem88

We got this to install at my grandma’s house. She uses a walker and often has trouble getting up as frequently and quickly as the dog needs to go outside. this is perfect because it alleviates the problem for both of them. This is not a job for one person to install – assistance may be needed to line it up and some kind of sealant might be needed if the cut isn’t perfect. But overall, I recommend! Also, I sized up to large because I couldn’t picture the opening size being enough with the medium, but probably could have gone with a smaller size since the dog has more than enough room.BRMomma

After reading all of the reviews, the VERY common problem is the hinge. This is going to be my 3rd or 4th door and second to purchase (the sizable hole is hard to find a replacement for), most EVERYONE has had the exact same broken and weak point of the hinge. Some of these comments are from long enough ago, you would think that the company would look at the common problems and try and fix the issue. But they seemingly have yet to make an attempt to fix the common and perpetual problem of the hinge!!! GUYS COME ON!!!!!!!! Not adding a photo, there are plenty of them on here already.Isaac09

I've had this door for a year now, and after a year of modifying, and remodifying, I give. Simply not a great door for strong dogs. Our doberman broke the door out initially, it was put back in place. The 2nd time he broke it out some of the plastic fasteners broke off. My SO ended up modifying the door with an aluminum strip and all new hardware. It's been broken off several times even with the new modifications. The key backs fall off and we didn't end up using them anyways to begin with. The frame is solid, we got the wall kit which is flimsy and had to seal ourselves but nonetheless it's installed. I'd love to order another model that will fit the already permanent opening. As of current, our heat's turned off until we figure out what to do to fix the door. It's not strong enough for large dogs, they bust it right out!Bunnyfromdahood

Purchased the door about a month ago. We have 4 dogs ranging in size from 6.5 lb to 60 lb. All of them use the door even the little guy. The big dog did not need any training at all he instinctively new when it went click he could go! I was concerned about the reviews but it seemed to me that these were all very large dogs by height and the photos of the installs seemed low to me. I would recommend the product. No more getting up two or three times a night. YAAA I installed it myself, granted I am more of a handyman than most, but I am also over the 65 mark +. So I would expect the young bucks to do it even faster. But you do need to have a supply of the D cells. Batteries are not what they used to be and you only get about a month or a little less use. I am concerned about how long the tag battery will last, time will tell. Great Productricky5437

In our old house we had this door and loved it. The door was on the north side of the house but always kept the wind, cold and snow out! So naturally when purchasing a different house, my first purchase was another door! This truly is THE BEST door! We substituted metal screws for the plastic ones. The door held up perfectly to our 2 rambunctious Schnauzers too!Terri Nevada MO

I would highly recommend this doggy door. This doggy door is very well made and sturdy. It has a nice piece to slide in when you want to block the door. My friend came over to install it yesterday and the instructions were clear and it even came with a template to help with an uncomplicated install. Now the fun part will be getting my fur baby to use it.Dreambiz

The advertisement for this door does not give you the measurements needed for the wall or door opening which would help in determined the size you order. They are not clear on the fact that this unit is for the door and not the wall. They offer a wall kit for more money if you intend to install this in the wall. The wall kit is not needed if you are a handyman type person but you will have to go to the hardware store and buy longer screws because they are only available when you buy the wall kit. Why not just put the screws in the kit to start with.Otis2

Excellent opening size for our pet who is 18 lbs. I purchased the Medium opening. Our sliding door is a custom height of 12 FT, not a normal height, so using the extension included with the patio panel still doesn’t reach the top of the sliding door, which of course is not the problem of the manufacturer of this product. We remedied the problem by using and cutting to size a disposable hard foam cooler, fitted with a foam edge window and door sealer in order to eliminate cool and hot air from coming in and out. It’s not perfect, but works for our pet and for our use.Grace

I currently own 2 doggy door slider inserts from a competitor brand. I got this PetSafe insert to replace one of my inserts that is worn out, and I am so glad I did! At first glance you can see that the PetSafe is far superior to my competitor door. Upon quick exploration, I could feel that the PetSafe door was much better quality. The PetSafe door itself is more substantial and heavy duty just off the bat. I like that spring-loaded panel at the top of the door is taller (than my competitor brand) so that it can accommodate more sizes of sliders. I have multiple different heights of sliders at my house so that gives me more options of doors for me to place the insert in. This is beneficial to me when I have a party for example because I can give my dogs indoor/outdoor access to a secluded part of my house when young children are over. The second part I really like is the extra security with the locking panel to close the doggy door. Whereas my competitor version only has a plastic lock that could easily be broken into by potential intruders, the PetSafe has a very secure metal pin lock. Third, I appreciate that this insert has a slight tint to it. My competitor version does not. When I open the doggy door in the early morning in my bedroom I "hook" my curtains around my original slider handle for my dogs to access the door and I go back to sleep. The tinting on this insert is at least some attempt to block out the daylight. Finally, I like that they include some weather striping to help combat some unwanted drafts. Although I would recommend to combo the weather stripping provided with foam weather stripping to really complete the seal. Overall, I highly recommend this PetSafe doggy door insert, their attention to detail is prevalent making their door superior to competitors.MamaBear34

I'm giving it three stars because it is working but for the price, I expected a higher-quality item. In some ways this unit is too thin for my patio door track and is floppy, and in other ways – specifically the attachment brackets and the door "latch" – it is too wide. I had to come up with another way to fix the panel in place, then insert foam tape because it kept flapping when the door was used or the wind blew too hard, and then buy separate security bars for the patio door. Not ideal. And I also plan that I will need to remove it if I leave for an extended period of time, as this thing is a serious security vulnerability in the home's perimeter now…not that most adults don't already fit through an extra large pet door opening. I wish this had a full closure panel – aluminum, hinged. Maybe I should have just made something custom since I can't cut a hole in the wall of my rental house for an electronic security dog door.Julie D

The SureFlap door uses a microchip to activate the cat door. My cat has always had a cat door but used to wear a magnet on his collar that would activate the door. Now I don't have to worry if he loses his collar because he can still get in. Very easy to program. Just push one button and the next cat (or dog) to walk through the door is recorded for the door. The door also has a curfew setting. This was gold to me. I had been paying a cat sitter $10 a day to open and close the cat door any day I was gone. Easily set time it opens or locks for the night. If locked, the cat can still enter, just not leave.Valski

Installation was a breeze as I replaced a manual cat door to this microchip controlled large cat door. My cats use a regular cat door so switching to this new door was really easy for them and the controls made it easy for me. Two cats have microchips implanted and the third uses the collar type and the Sure Flap Microchip LARGE Door works seamlessly for all. I used the unlocked mode till all three cats used the door than set it for ID registrations till all three had been through and registered. After this I set it for 10 second delay, then 2 second delay and now no delay. What an excellent quality door and so easy to program. I recommend the large door as I have a 15 lb., a 12 lb. and a 5 lb. cat and it works great for all of them.barbsmh

The Sureflap is a great product, easy to install and by following the setup guide, quite easy to program. It has stoped the neighbors stray cat from making itself at home stealing our own cats food and the fights when it would just come inside. My only problem is to somehow get our own pet cat to want to use it. Seems to be quite stuborn and will not exert enough nose pressure on the flap to overcome the magnetic latch. I may need to carefully dismantle the unit to remove the magnet and then see what happens. I would definitely recomend this product to anyone who wants to have control over both movements of not only their own cat but anyone elses as well.Graham

I have looked everywhere for a big doggie door, I have a huge 110 lb German Shepherd and he was hitting his foot on the bottom of the old door I had in. It got infected and he had to have surgery. Long story short I found this big door and my dogs happy so that makes me happy. Plus I found other doors but you had to pay extra for the part that you put on to keep them in or when you're gone.Granny 3

This is my second purchase of this door for my cat. Overall, a decent product. First one, the cover was rather loose, but worked. The second one, the cover was too tight, could NOT get it off, not even by prying all around the flap area and edges. Finally, in frustration, I called Petsafe to see if I'd done something wrong. Was told there have been some complaints, that I could try cutting it off and they are sending me a new cover. Hung up and looking at it thought hm, could pushing on the middle while lifting on the flaps help. Guess what….it snapped right off.Dodi78years

I bought a petsafe pet door fourteen years ago. I live where it gets to a hundred and ten or more in the summer. After seven years the plastic flap warped and so I bought a replacement flap. It has been another seven years and again the flap is warped but they no longer make the replacement flap for the xlarge classic door. I found this at newer version at petco for seventy four bucks and bought a discount gift card so I was able to just replace the whole dog door for sixty two dollars. I figure its good enough and will outlast my dog.cami62

Easy enough to install, but their use of nylon bolts is a downside. I understand it is so you can cut the excess away. But it probably wouldn't have cost any more (possibly a tiny bit more) to engineer the door to use metal hardware so it wouldn't strip as easily. The other issue I have is the "security" snap on door. Because it's snap on and not slid in or lockable, both my dogs have been able to push it off from the outside in. And the door is XL so it's big enough for a person to crawl through, so there is absolutely no security from a person entering standpoint. Other than that, the door works perfectly well for letting the dogs in and out independently, and keeping the heat/cool outside.Chefblue

This was dribbling enough water into my utility room during storms that I had to disassemble it to figure out where it was leaking. I couldn't find exactly where it was letting water in, so once I got it reassembled, I caulked the heck out of it and it seems to be okay for now. Taking it apart and reinstalling it was a major hassle. Most of the nylon screws either broke or wouldn't fit all the way back through, after numerous attempts. Seems to be poorly engineered. And the door where it was leaking isn't even facing in the usual direction of the wind/rain, so I don't know why it leaked so badly.TS777

Dog loves it but presentation is misleading. It does not show that it needs to be plugged into a power supply or you need to purchase an additional battery pack. But after spending the additional hundred dollars for the battery pack it allows the dog to easily go in and out, but remember to change the battery out every two weeks or the dog will get locked outside in the middle of the nightCelestecatcrazy

Learn from my mistake and run far away!!! This door was somewhat convenient when first installed, but I quickly found that the transmitter didn't always work, which left my dog inside or outside at times. However, with the first hard rain, this door became a disaster. The door flap leaked water all over my floor, both under the flap and down through the body of the dog door. I didn't discover the flooding until a large puddle had developed, warping and splintering my hardwood. I spent two hours on my knees mopping with towels and trying to seal things with duct tape as the rain continued to flood in under the flap opening. When I called the company, I was told that, since the door had been purchased over 90 days prior, that "the credit card company won't let us do a refund so we can't" (obvious untruth) and that the owner would only let me return it for store credit. They had no interest in finding out what the problem/defect was and trying to cure it or change it so as not to do this to other consumers. I'm was already out the cost of the purchase, hiring a contractor, and having it installed, and now I have to buy a new door and have it put in, as well as repairing my cupped, splintering flooring. Do they really think I'd want to have store credit to buy another one? This failed experiment has cost me well over $1000 so far. I'd suggest avoiding any of this company's products, and particularly this one.BusyBadgerMom

The door itself works great and at first all was good. Unfortunately the door only works with the collar which is junk and even after you buy their expensive batteries will not work because it is junk. Honestly the first time your dog gets the collar a little wet, for example running through sprinklers it will stop working. Do not buy.aaron.brown03

It is only a cheap piece of plastic not really worth the price but what else are you going to use so you just have to pay for itfastcds

Easy install and worked perfectly. It was a little tight when the tape was on. Just use one layer and it will all be fine.Welshmanusa

The door is well made and easy to install. we bought the large bronze. Only problem we have is that we have 3 dogs and one is a pug, other two are big 80lb even though rated for 100lb dogs and I measured them, for out dogs was a little short., I fixed by adding a small block under raising it an inch. but the 4-5' rise really does work for small dog. The XL version may have been better. But only came in white and more expensive. Been a couple weeks now and the bigger dogs are doing great. Pug, we open the slider for him. Overall well made and works well. Just a matter of getting sized right. May not work as well when you have a mix of small and large dogs.RichardJ

I bought this and installed it myself (after watching the video). Quick and easy install. Took a little coercion to get her to go through the door. She loves it now! Saves me money because now my cold air is not escaping through the open door. And best of all, no more mosquitoes and other bugs coming in my house. 🙂CindyZoey

I ordered this Ideal Pet Door from Walmart.com to replace the same model Ideal Pet Door originally installed over 10 years ago. Walmart.com had the best price and ordering from their website is convenient with fast shipping. This Ideal Pet Door is the same model with slightly different modifications which makes it a better door than my first one. Removing the old door was very easy to do. Replacing the new door was just as easy. All I needed was a Phillips head screwdriver and my fur~kid supervising me. BTW, The original installation took an hour and was placed into a glass storm door with a solid lower panel. The Pet Door is sturdy and comes with a panel that slides into slots on the inside to block the pet door opening. It can be used when travelling or when you want to keep your pet in or out. It has a magnetic strip on the bottom part of the frame and one on the bottom of the flap which keeps the flap closed. I have never had an unwelcome guest come through the door. The Ideal Pet Door is a great value, construction is flawless and replacement parts are available. It has lasted through years of two rambunctious very bad black labs and I am replacing it by choice. It can be installed in doors, storm doors, sliding patio door inserts and in brick walls. Ideal is well know for their quality pet products and has been in business for decades. I personally wouldn't consider any other manufacturer.tami76137

Extremely easy to install.* Looks and functions better than expected in an interior door. The screws were a bit long considering the width of the door. I would suggest using shorter screws because they were hard to screw in completely, and I was using a drill to drive the screws! Overall, the door is an excellent value and I would buy another one if needed. I went with a slightly larger door than typically recommended for cats. One reason is that we are expected one cat to grow large. (We think he's a Norwegian forest cat. Before that we guessed Maine Coon.) Also, there are steps immediately on one side of the door, so I figured extra clearance would help. The smaller door would probably work OK for normal sized, fit cats. (*I traced the part that slides through the door, drilled holes where the screw posts fit through, and just cut along those lines with a jig saw. It fit right through perfectly the first time! I had a moment of minor shock when I wasn't sure if I oriented the door properly since the middle screw posts are not centered. I did, but it would have been a correctable mistake.)shuumai

I did a fair bit of homework on dog flaps, reading reviews and sizes and prices. I decided to opt for this, turns out its very good. However My dogs wont go through the actual flap, to solve this i attached some string and a small hook to the outside to keep it up. Problem solved they go through the hole no problem. Be a bit chilly come winter but its just whilst im out. So overall yes i would recommend it.mazza7109

Great item and looks good. It saves me having to get up and open the door all the time. With the addition of the safety door , I know I can go away for a few days and still feel the house is safe and secure. It's great value for money.obsessedminiturist

The dog door works well once you get it installed. The plastic slats that line the inside passage are very hard to keep in place while trying to screw the inner and outer frames together. Definitely takes two people to install.Steven

Had one of these for about ten years and bought a new one. One of our dogs damaged the old one by trying to run in when the panel was inserted to keep him out while a worker was in the house. This broke two of the screws away from the plastic frame. Even though it says aluminum pet door, the only aluminum part is the white door frame. The brown frame around it is plastic as is the wall tunnel. Since we now needed to replace the flaps, it costs just as much to get a whole new one as it did to replace the flaps. Now for the new one – Had it installed for less than a month and spring loaded knob on insert panel is broken (called for free replacement under one year warranty). Door panel flap lengths are adjustable, but don't seem as thick (and durable) as old ones. If this hadn't been a replacement project of an existing one, not sure if I would have decided to install this one or look at other options.AZTom

I am on my 3rd PetSafe door. I started with a smart door but I got tired of constantly changing batteries. I have 4 dogs. I got the double flap door. After about 1.5 years the plastic piece that holds the flaps started to break (little pieces at a time). There is no replacement part for this so I had to purchase a new door. PetSafe did give me a reduced price. Now, I have gorilla tape holding my one remaining flap on this door,since the same part is breaking once again. This part is cheaply made and I feel like you should at least offer a replacement part. Now, I'm facing buying another door…again.Crazydogmom

This is a great dog door for a medium size dog. It is a deluxe unit with dual flaps for maximum weather protection. It also has a slide-in closing door with a secure lock. It looks stylish and it fits (one of our main concerns) through the section of the house that has brick. We had a professional install the unit, unfortunately, it was a little higher on the outside than the dog would have liked (see picture above) which hindered her from going back into the door. I solved this problem by ordering something called the Ten-Eighty Mini Launch Ramp for about $30. It is designed for skate boards and bicycles but it will also work in this application. I needed a little modification to sit flush with the wall and I had it carpeted so the dog wouldn't slip in cold weather. Now the dog goes in and out of the door effortlessly. I hope that this idea helps others in consideration of this great dog door.norman3670

My husband checked all the various reviews for dog doors before buying this Plexidor model. This one had the best ratings and now we know why. He installed in the garage wall. Instructions were easy to understand and the door works great. We love it! We highly recommend this door. Kyle and JoanneJoanne K.

I just installed this door and it doesn't come with the RFID collar and they make it impossible to purchase. I'm literally leaving this review while I have a robot "agent" pass me around from person to person trying to find the right collar…Coopaloop3456345645

Now that I have it I couldn't live without it. It has stood up to my three large dogs for a year and half so far. We haven't had s problem yet.Sarah L.
