Extra Large Automatic Dog Door For Sale (2024 Update)

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

i really like this door. no more getting up every few minutes to let the furbies out. even my lanky border collie mix can crawl through. very sturdy. would recommend.Snowcat

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 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

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

This is an AWESOME dog door solution. We purchased ours in 2011 and it works great. INSTALLATION: I’m not handy so we had a carpenter install the door. It wasn’t a problem for him. We live in an old house so rather than cut the original 1920 door, we bought a door from Home Depot. TRAINING OUR DOGS:: It didn’t take long for our dog to learn how to exit the house and reenter the house. WHY I LIKE IT; Versus a flappy cheap plastic door…this has two major advantages (1). More secure. For a large door, a flappy door can be easily broken into (just crawl in!) where this door would require force and would set up an alarm, and (2). Very weatherproof. The seal is tight, so hot air (summer) and cold air (winter) doesn’t continuously lead in. So there is a comfort and a cost savings factor. DURABILITY: In 7 years (Our dog uses the door about 5x a day, so that is about 13,000 up/downs!) we have had 3 issues. The incredible customer service person (Deidre, who has worked there for about 20 years) is extremely knowledgeable. She walked us through one problem in less that 5 minutes. She helped us fix another problem which took about 20 minutes. And the third issue required a new circuit board which under warranty was free (and out of warranty about $80) and once we received it, took about 15 minutes to install. My wife and I used to work at Purina for 17 years and 12 years respectively, so we know alot about dogs and cats. Our jusdgement is this door, although costly up front, is very well worth it. Don’t know the life of the door, but I would expect it to be longer than the 7 years we have had it. So if it good for 15 years, it costs about $120/year.ScottRod

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.

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.

I bought this a couple weeks ago, and immediately had trouble. For some reason the collar was not easily recognized by the door to open for my dog. I'd done a lot of research on electronic pet doors and was disappointed. I e-mailed customer service, especially since the collar stopped working altogether 9 hours later. Within 24 hours the CEO of the company responded to my e-mail and they sent a replacement collar within the next few days. This new one works great, and it was really great to know the company was responsive to issues to this expensive item. I think the collar was a dud and an anomaly, but would definitely recommend this door to others willing to make an investment. The cons are the high price (I bought when there was a sale online) and like most patio/sliding glass dog doors, it blocks the built-in lock from the door to the wall. The door comes with an alternative lock, that can be drilled into the door, but it didn't fit mine. I think we will just use wooden dewars to block the sliding door in. I also bought rubber weatherstripping to help seal the door to the dog door and prevent air-leakage.Wynnie_thecorgi

The only improvement I would make is to have a way to insert the battery pack at the same time as being plugged in. The whole point of having the battery pack is to have a backup in case the power goes out and your not at home…Laura A.

I don’t understand why this is sold as “great option” doesn’t make sense…. If I fit this in the tracks and assuming that it’s a perfect fit, The passageway for humans to walk out is wayyyy too small! You need to dedicate a whole sliding patio entrance only for this item, do not have any hopes that you’ll be able to use it to go in and out or carry something outside, you won’t fit thru it!Amosh83

After comparing price, style and weather insulation, I found Petco had the right patio door. It was easy to assemble, looks great with the matching white trimming and seals perfect, no cold air coming in. The price was just right compare to others. My pets love it, no more getting up to let them out or leaving the door open.mancha2247

My insert is 5 years old now and still my dogs favorite. In the winters the UltraFlex 3 panel dog door keeps the cold out. Yes it does cut down the human passage, but its still very passable. Unless you have a non-standard sliding door.Stand77

I knew when I ordered it it was going to be a little big, cut 3 inches off the bottom an fit perfectly to my sliding door. Everything included that I was to get in box. Priced better than Lowes an other places checked, previous door was plastic an the sun faded plastic, but tempered glass is really nicedavidpoole2011

It wasn’t till I saw the warning on the box that I was aware the door insert was not compatible with my vinyl door. However, I found it was not difficult to adapt it. I would not have ordered it if the warnings on the box were as stressed on the on-line ad. At the same time I’m happy I bought it, as it is securely in place, is of high quality and the price made it a bargain.LFritz

I received this locking pet door from Try it Sampling Company for free to test out. This pet door is convenient for my cat to come and go during the day. It was easy to install and use. I would recommend to install at a back door/back porch area. To me it looks better than being at a front door. Great ProductBDom

The size is perfect for my little 6 pound Malti-Poo. I wanted one that a child could NOT climb through and this one is perfect. It is not like a regular dog door where the flap in a thick piece of rubber. This door has a solid plastic flap and my dog will have to learn to use it. This morning he came in through it but has not ever gone out using it. Will take some practice.mountainmama7

Love the build! I hope my fatty can use it for as long as he lives. I gave it 4 stars because I am concerned with quality and breakage in the coldRachelle

The inside and outside frames are good rigid aluminum and are preassembled to the rectangular shape. HOWEVER the tunnel is an assemble yourself and does not work well on newer homes with 2 x 6 wood and stucco walls. They are not wide enough to go from inside wallboard to the exterior stucco. I had to fashion my own add-on pieces to make it work, hence much more work. Good construction of the components, BUT not sized well to fit through a wall. Doors are probably OK.Hay Ed

This is a really solid door with a good metal frame and a unique thick flexible door flap with multiple magnets. We have the extra-large version. It took a few days for our Labradors to get used to it, but they seem pretty comfortable with it now. While it's certainly not "air-tight" it's perhaps the most tightly sealed dog door I've seen. High Tech Pet customer service was great with the one small issue we had.Georga Lab Dad

Very happy with this purchase. Sturdy aluminum construction with a truly unique flap that is wind and weatherproof. Far exceeded my expectations. A little pricey but, definitely worth it.BigDawggie

Our older dog is infirm and has become intimidated by the pet flap, and started peeing on the kitchen floor at night, in spite of our efforts to retrain him. I was concerned the dogs would be afraid of the Autoslide opening the door, but both dogs took to the Autoslide immediately on the very first opening. I'm using the wired infrared sensors; they work reliably but do take some time to aim and set the sensitivity properly. I popped off the door casing (molding) and hid the wires behind, which makes it all look finished. Have been using the Autoslide for several weeks now, and I'm overall very pleased.Richard L.

I have had 2 different handy come out to try to help install this unit after spending 3 hours on my own trying to figure it out, and both told me that its not possible to mount on my door. DO NOT BUY this unless you have a large metal sliding door or one that goes to your ceiling otherwise you will not be able to install. I have tried calling Autoslide multiple times to get assistance and now return the unit and no response.Nicole M.

I like this device. It does everything they advertised it would do and had everything I wanted it to do. In my particular situation, I had a very difficult installation, Autoslide had an answer for everything online. When I had a very minor problem, I contacted Autoslide online and they provided the answer in a couple of minutes. Great product with the expected safety procedures built in. Would buy again.Robert T.

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

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

I didn't realize that this works only on certain types of screen door. Mine has a retractable screen on the inside. I see no way for it to work on the inside. I also can't put it on the outside because it isn't weatherproof. To use this, I'm going to have to remove my beautiful sliding glass door and replace it with an inferior brand.Anonymous

We have had our door since about 2004. The product is top notch. I don't think Plexidor was making theirs at the time but this is about half the price. I have very large dogs, this is much more convenient to allow my dog to be able to get out when they need to; but it doesn't allow intruders in. Especially now that they are older. One of ours is slightly to tall for the door but she ducks to get through it. The only thing I wish is that they made this one size taller. With a really big dog that's the true problem is stopping people from crawling through your human sized dog door. I have never had problems with my collars, though after losing two dogs years ago we misplaced one collar and ended up buying the MS-4 eventually to replace it. But they all work. We have the invisible fence collars to, but found them bulky especially with the prongs. We didn't like the rechargeable collar, wasn't worth the extra price. Didn't work w/ the larger dog since she was to tall and the smaller dog hated it since it was big and bulky. It worked with the invisible fence system also, so it had the big prongs to. Stick with the MS-4 which you can get the most reasonable currently. But we have a old MS-2 that is working still 10+ years after we bought the system. My only issues are that I would prefer to have a system that used the RFID technology and I would really love if they would make a taller dog door. My dog is easily 25"+ high at the shoulder so she ducks through the door. But it's not cost effective to buy the Plexidor instead, when it is not taller and I have used the Power Pet door successfully for so long and I know how well it works. Batteries in the collars last a really long time, longer than I expect them to. I think in the past year we may have changed them 3 times. Occasionally one of our dogs takes out a battery a little sooner by going for to many swims in the pool, pretty sure they are only water resistant as of the MS-4 still.Alysa

Better than expected I have a corgi 40lbs and. Pitty X both dogs 30 lbs they love the freedom of going in and out no more waiting for me to come home from work to go out. Was easy to install wish the medium door was a little bigger corgi just fits. Overall very happy!!Catherine

Our dog has a chronic issue with colitis. He can't hold it more than 4 hours. He gets up several times a night to use the bathroom. it's almost like having a newborn. In the past this has made our lives difficult. Paying for expensive daycare, or having to take extra time at lunch to come home and let him out. If we went out with friends we had to make sure we could stop back at home after a few hours to let him out. It also interrupted our sleep every night. (For 6 freaking years!!) And due to the colitis, cleaning up after, well let's just say I don't remember the last time his stool was hard. So this technology has been a true godsend for us. Our lives have been soooo much improved by buying and installing this door. Rockets life to. It really has been the best investment we have ever made. When we bought the door we were in the process of moving and it's been 6 months now. We lost the screws that came with the kit and ended up buying some. I was afraid they wouldn't fit perfectly and the door would fall off or cold air would get in the winter. So far so GREAT. We are still on the first battery and it has really worked well. Our only issue, after 6 years of asking to go to the bathroom, whining or pacing at the door, Rocket still sometimes begs us before he remembers he can use the door himself. This is amazing, thank you sooooo much! Highly highly recommend!!darbydh
