Dog Door Training: 4 Reasons I Hate Them and 1 Reason I Love Them

If I had a nickel for every time someone with a doggy door came to me because they were having puppy potty training issues… well, I think I would be a millionaire sitting in my pool writing this. 

Unfortunately, it doesn’t work that way for me! But, as often happens after umpteen million questions regarding one subject it dawns on me that perhaps it is time to write an article to help people.

So, here is a guide on how to train your dog to use the doggy door, as well as a few reasons why I am not a fan of the great doggy door. And don’t worry – at the end I will tell you the one reason I like them if used responsibly!

While some dogs immediately understand the ins and outs of maneuvering through a pet door, others need a bit more training and encouragement. Here are some tips on how to train your dog to use the pet door and some techniques to help them through the first, most difficult step.



The First Step is a Doozy

Some dogs seem to have trouble taking the first step through the door. Some will step partially in or out, but not all the way through.

To help your dog walk through a pet door, position yourself and your dog on opposite sides of the door with you on the inside and your dog on the outside. Then encourage your dog to come in through the pet door with dog treats or targeted commands like, “Come!” Practice this dog training technique several times until your dog walks through the pet door door

If your dog still won’t walk through the door, even after several attempts using their favorite treats, there may be other issues preventing safe passage.

The door may make a strange noise that frightens your dog, or the step down from the pet door to the ground may be too steep. 

Check to make sure your pet door is working properly by pushing your hand through to test it out, and thinking about it from your dog’s point of view.

One of my dogs struggled with the pet door a bit until I realized that going was scary for him because there was a big step down. So I put up a ramp.

Electronic doors like the PetSafe Electronic SmartDoor are great because they open automatically when triggered by a key worn on your dog’s collar. Most models make a sound then activated, which can be jarring for some dogs. If the sound bothers your dog, turn off the electronic portion until she is comfortable walking through it. Then re-introduce the electronic portion gradually using positive reinforcement like treats and praise. Hale Pet Doors are also generally a really great option if you want a more traditional doggy door.

Avoid forcing your dog through the door. This can increase the anxiety they associate with the door and cause them to resist using it even more. The keys to success are consistency, patience, praise and a lot of dog treats so that your dog will open the door itself.


History of the Pet Door

There’s no doubt about some of the wonderful attributes of the pet door. 

Sir Isaac Newton invented the dog doorBut who actually came up with the idea is still a topic of debate. Some credit the ancient inhabitants of Cyprus and Egypt who made simple holes in their storage houses so feral cats could hunt the rodents that fed on the grain and flour. Geoffrey Chaucer described these “cat holes” in the “Canterbury Tales” during the late 14th century.

But the most popular theory credits Sir Isaac Newton with inventing the pet door. 

According to an anonymous report published in 1893, Newton mistakenly made two holes in his home, a large hole for his adult cat and a smaller one for her kittens. The scientist discovered too late that only one hole was necessary. The kittens simply followed their mom through the larger one. Sadly, drywall wouldn’t be invented for another 20 years.


Dog Door Training

Most pets are eager to explore the outside, and once they realize they have the option to go in and out as they please, they will jump on the opportunity. Teaching the pet generally takes somewhere between five seconds and five days.

Whether you have an adult dog, or a new puppy, teaching him how to use a doggy door will be done the same way.

When you install your dog door, make sure you measure the "rise" of your dog (the measurement from the floor to the lowest part of your dog's chest or stomach). This measurement tells you where to place the "bottom" of your dog door. 

The bottom of your dog door should be an inch lower than the "rise" of your dog.train your dog

If you have a puppy you will need to install the dog door one inch from the ground; and you will need to reinstall it at higher intervals as your puppy grows.

Another option is to take an educated guess as to how tall your dog will eventually be, install the dog door at the appropriate height, and construct a "puppy-ramp" so your puppy can reach the dog door and go through it comfortably.

Once the frame of the doggy door is installed in a wall or door, leave the dog door off at first. Have someone stay inside with your dog while you go outside. Call your dog through the "hole" (door frame without the doggy door). When he goes through and comes to you, praise him lavishly and give him a treat. Now have the person inside the house call him through the "hole." 

When he gets to them, they should praise it and offer a treat as well. Do this at least 3 times and no more than a dozen. After this, your dog will know there is a hole in the wall or the door especially for him.

Leave the doggy door off the cut opening for one full day. Encourage him to use his opening by not letting him use the "real" doors. Instead, you use the real door and say to your dog, "Go to your door!" pointing in the direction of his dog door. You may need the help of someone inside to "help" the dog find his new door. After a half a dozen times, your dog should like this new game! 

If you have a very young puppy, do not expect them to learn "Go to your door" for many weeks or months; still give them the command in a happy voice, and have someone inside show them where their door is every time. It sometimes helps if you are outside (after going through a real door) and someone else helps your dog or puppy find the doggie door as you call him from outside.

On the second day, install the doggy door. Now, you will need to repeat the same exercise as when you first sent your dog through the "hole." But this time, the person on the same side of the door as the dog will need to "push" the dog door open for him. Each time the dog goes through the door, push the doggy door less and less for him. It is important that the dog gets used to the feel of the dog door on the back of his head so once your dog has begun going through the door, let go of the pet door so he feels it on his head and body as he goes through the door.

pet doorsEventually, the dog will need to push the dog door by himself and dogs are usually hesitant to do this at first. He will probably put his nose down by the bottom of the doggy door and wait for it to move (after all, it has up to now). At this point, push the doggy door slightly so that your dog can see it is a movable object. Let the door bounce back to the closed position.

The best way I can explain it is that you are "poking" the doggy door using short, quick pokes. This gives the dog a glimpse of an opening and encourages him to poke the door himself. At this stage, some dogs begin going through the door with ease, others become quite excited, but still haven't figured out that they can push the door open.

If your dog will not push the door open by himself yet, remove the doggy door and install a piece of carpet onto the opening. You want the carpet to have a least a 1/4" to 1/2" opening on the sides and bottom. The dog should feel more comfortable pushing the carpet on its own. After 2-3 days, install the dog door again. With plenty of enthusiastic encouragement and praise, your dog should be able to push the doggy door now with no problem.

Make the pet door a part of your house training by using the same technique outlined above with your puppy on the outside of the door and you on the inside. Coax your puppy through the door with treats and give them plenty of praise.

Make training fun by playing peek-a-boo through the door or by squeezing a squeaky toy to get their attention. To housetrain your puppy, have them use the pet door to go back outside, then meet them there with a leash. Take them to their designated potty spot and wait until they use the bathroom. Remove the leash and have them use the pet door to go back inside.

You can also place a toy outside the pet door to help your puppy understand where they need to go. Gradually move the toy away from the door to their designated spot. Practice several times, and before you know it, your puppy will be pet door pro.

Using the pet door comes naturally to most dogs and cats, even if they are reluctant to use a traditional rubber flap door. They can see outside through the clear panel and the panel swings open's nose

If the pet doesn’t take to the door, try propping one of the panels open and coaxing the pet through with a treat. When it comes to cats, it generally works well to put something they want on the other side of the door.

For the electronic door, it usually works well to put a treat on the bottom lip of the pet door. The dog or cat approaches to get the treat, and the collar key triggers the door to open. It doesn’t take long for the pets to figure out that the door will open when they come close.

Some pets need longer than others. It is important to stay patient and calm, and give praise once they do come through. When the get the hang of it, they’ll be happy to run in and out without having to wait for a human to get the door.



Reasons Why I Don’t Like Doggy Doors


#1.  Doggy Doors Impair Dog Potty Training

People are under a severe misunderstanding that if they put in a doggy door, they won’t have to worry about their puppy having accidents.

Unfortunately, most of the time, actual potty training doesn’t go into this process. Let me tell you that puppies don’t come out of the womb knowing that they should pee and poop only in grass.potty training

In fact, some breeders whelp litters on kennel or concrete basement floors and so these puppies are used to hard, slick surfaces to go potty. So, in these cases, some puppies will go outside to play and come inside to potty.

Also, it is important to note, that without actual potty training these dogs and puppies get used to going potty wherever they are and whenever they feel like they need to potty.

I suppose we can liken this to babies and diapers, they just pee or poop when the mood hits, except most puppies (provided they are old enough) can learn to hold it; just like young children learning to potty train.

They potty outside, they potty inside and the truth is they don’t know any different if time is not put into actual potty training.

If people want to use a doggy door, I recommend sealing it up completely until the dog understands and is fully potty trained.  It is a lot easier to teach a dog to utilize a doggy door to go outside than it is to do both this and potty training at the same time.


#2.  Doggy Doors Can Facilitate Bringing Dirty Creepy Things Into Your House

dog doors allow your dog to bring things from the outside indoorsAh, the good ol’ doggy door! Not only does it allow your dog to go outside anytime he desires; it also allows him to bring the great outdoors INDOORS!

If it rains and your backyard is a swamp, muddy paws and muddy bodies have full run of the house! I have a dog that LOVES to splash and lay in a good mud puddle on a hot day.

Let me be the first to tell you that I don’t want her on my sofa and on my bed, much less wandering across my floor. When I let her out and she does this, I can wipe her feet or hose her off or bathe her prior to house access.

If your dog finds and kills a mouse, or has the good fortune (for him) of finding a dead critter in your yard (or poop, or pine cones, or well… you fill in the blank) that too can be stuffed in your bed, in your sofa or just splayed out on your floor.

Dogs will be dogs, and dogs can be smelly people! No, thank you.


#3.  Doggy Doors Allow Your Things to Go Outside

This is also a BIG one I hear about!

Like your laptop? Leave it out on the table? It may end up taking a little travel around your yard!

Michael Kors purse or bag lying about? Hope you don’t mind finding it outside.

Even if it is not shredded beyond recognition, chances are having expensive things take a stroll through your backyard is a distinct possibility. I have even seen pictures of things that I could never imagine getting out of a doggy door, out in someone’s backyard!

If you leave your dog out (hence the doggy door) you can’t lock everything down… I have seen couch pillows drug out big doggy doors! Again, no thank you!


#4.  Doggy Doors Allow Wildlife to Visit You

I remember dog sitting for a dear friend of mine.

We went through the regular “how to” of the pet sitting for her house and she described how I needed to “lock” the doggy door before I went to bed. I couldn’t quite figure out why since the dogs were safely and happily in sleeping crates at night. Then she described how a raccoon had been caught “red handed” in the dog dish one night and the fun that happened after his discovery, trying to then get him OUT of the house.

If your dog can get in, so can other animals. And, as you can imagine, starving wild animals can be quite scary when they are challenged. It’s likely that they come in because they can actively smell the food. Most of us are asleep when wild animals peruse our homes and garbage. A door is a door to a hungry critter. And, some wild animals carry Rabies. Not to mention a wild animal coming into your garage and home can seriously hurt your dog.

Not all visits happen at night, too!


And the One Reason I Like Them?

If…  and I mean IF you potty train your dog, and train your dog, and trust your dog and work long hours they can be a life saver. Adult dogs can go long periods of time without having to go outside. After all, most of us don’t have doggy doors and our dogs do just fine.

But some jobs require 12+ hours, and for those people who (hopefully only occasionally) work those hours, a pet door can allow them to own a dog. I know it is not ideal to be gone that long, but sometimes life is hard for us humans too.


Some Quick Tips

I DO use a doggy door, or should I say “kitty door” that leads into the room where I house the cat litter box! And, for that, a doggy door has been AMAZING!

Teaching your pet to use a pet door is usually a quick and easy process. Most cats and dogs learn to use a dog door immediately, although some take several days. Do not push the pet through the door. Start by propping open a panel and coaxing the pet through with a treat.

The following tips will make learning easy:

Put something your pet really wants on the other side of the door. This could be a favorite toy, or an extra delicious treat. Dogs like things with interesting smells, and most dogs will want to investigate a piece of smelly cheese.

Prop the door open and call for your pet. Praise any progress. It’s important to be patient and maintain a good mood. Babying the pet proves the door is something out of the ordinary and should be feared. Forcing the pet through has the same effect.

If you have a door larger than small, so it has two panels, start with keeping both panels propped open, and when your pet goes through the hole willingly, close one panel, to show that they will swing open.

Give more praise.


The Bottom Line


In reality, how useful or counterproductive a pet door can be isn’t universal. It depends upon your situation, your dog’s personality, and how well that your dog is trained. If your dog doesn’t like your pet door and you haven’t trained it to use it, well, then it’s just an access point that other animals can use to get into your house. 

If you have a dog that likes to get messy, having a way for it to come and go as it pleases probably isn’t the greatest idea.

However, if you trust your dog, and, if it’s trained well, then pet doors can be amazing for allowing your dog to come and go as it needs to while you’re working long hours at work.

    Are problem is our dog uses the doggie door to go
    When there is no other option. However when we take her out of the corral and the door is a distance away she pee’s
    on the tile floor which is 10-15 feet away. She is only 5 months old so we may be expecting too much to soon.


  2. joan.theiss says:

    i have a miniature dachshund that will be taken out for sniffs the grass, sometimes he rolls on his back…but no matter how long you have him out for, he still saves his peeing and pooping in for the house. i live on the 3rd floor with a balcony which has been puppy proofed with chicken wires. is it safe to put a pee pad out on the balcony and watch for the signs [sniffing the pee pad before he goes] and rush him out the door? i have put grass on a pad to see if this will entice him, but to no avail. he is a year old, got him at 4 long should it take him to learn to go outside?

  3. Retha White says:

    We do have a doggy door from prier puppy. We are now trying to train two puppies to go out whenever they need to pee or poop. We find the puppies will go out side and sometimes not pee and walk inside and pee on the pee pad.
    We can’t understand why the puppies do not pee while they are outside.

    I have a doggie door that 3 dogs and 2 cats use. I have had no problems with the dogs behavior because they were potty trained before the use of the door. Except one, I potty trained him using the door. They may take their toys out occasionally, what kid doesn’t? The cats are the worse, they bring me “presents”. LOL


  6. Erinn says:

    Hi! I have three dogs, ranging from 5-20 lbs and 1yr- 5yrs. They have a dog door to our fenced yard and during the day I have gates up so they only have access to outside and the dining room area. During the day they all potty outside no problem. It’s night time that’s an issue. Even with the bed room door open they don’t go downstairs/outside to make. My Pomeranian that passed away had no problem, he’d sometimes make the trip downstairs two or three times a night but none of my three dogs do. Every morning I wake up to poop and pee, I have to steam clean every weekend. The youngest pee’d on my bed this morning because I slept until 8. They’ll only go downstairs if I’m with them. How do I get them to just use the dog door downstairs whenever they have to go? Thank you. My husband and I are at our wits end, we love having all our dogs in bed with us to cuddle at night. I don’t want them to have to stay downstairs (which we did try for a month) I just want them to make that quick trip to the yard and come back to bed. Help please!


  7. Ashley says:

    If anyone can give me some insight! My 4 year old dog was perfectly trained for the doggy door, never an accident inside. Now we moved to an apartment where we don’t have one and she is pottying inside constantly! I take her about every 3 hours but still in between – or if we leave for an hour, sure enough she goes inside. Even if she goes right before ! Help! I’m desperate! She is a great dog with no real marking problems. It just seems like she doesn’t get it. Help!!!


    Minette Reply:

    She probably doesn’t because she was able to potty whenever she wanted before, part of the reason I hate dog doors. You’ll actually have to potty train her now



    I have a 3 1/2 old labrador/shepherd mix who was fully trained and fixed when we got her at 1 1/2 years old. We have a dggie door she uses without a problem. However she likes 2 pee/poop on the only two carpets in the house. And occassionally poops in a 3rd room. She does this and we have no knowledge until hrs later when its too late to correct her. I dont walk her every day. She is healthy. Is this a result of not going for a walk regulalry or is there some other solution? Most advice addresses people who dont have doggie doors and when poo behavior is seen as its occuring. Its become frustrating and it is hard to keep the offending rooms closed off.


    Minette Reply:

    Doggy doors don’t teach dogs to hold their bladder or feces, they can “go” whenever they want… so it is not hard to see that the dog doesn’t understand the principle of not going potty whenever and wherever she wants.


  9. Angie says:

    I wish I had read this before we got a new pup. We got a doggie door when our last dog had kidney problems and was 13 years old and couldn’t hold his bladder anymore. It was great. It took forever to train our new puppy…he’d run inside to pee. Now he’s mostly housebroken…except that he’s taken to peeing ON the doggie door. I’d say randomly, because I used to think it was during rainy weather but now I’m not sure what prompts it. Once every couple days…not daily. I’m going out of my mind! Any ideas?? Help!


    Minette Reply:

    I would go back to crate training or using boundaries and not the dog door


  10. Sarah says:

    I have a puppy who is just about 3 months old. She has learned that if i take her outside, she will get a treat if she pees or poos. She has learned that if the older dogs go outside, she will go with them and pee/poo when they do. BUT…if left to her own devices, she will not go outside to pee. (We haven’t found any poo so either she takes herself outside for that, or she poos when the other dogs poo and that’s why we haven’t found any.) She will pee in front of the doggie door. Any suggestions? The weather has been good lately, but we are in the Pacific Northwest and I fear i will be cleaning up pee all winter!!
