Help! My Dog Won’t Use the Dog Door

Dog doors offer a great convenience to fur parents to give their pooches access to outdoor spaces such as yards or balconies. Who wants to accompany their post-puppy-stage companion to the toilet spot every time nature calls, especially at night time? Depending on their age and health, it can also be rather inconvenient for your dog to hold it in. Some bodily organs have limited patience and no regard for convenience. So, if you come home or wake up to a mess, please never blame your furry friend.

Identify the Culprit Behind Your Dog’s House Soiling

When your dog soils the house, there can be a range of reasons. What is certainly not the reason for leaving unpleasant surprises on your beds or carpets is any sort of intentional depositing, for example out of ‘revenge’. Sometimes our brains are too complicated for their own good and spin a story where there is nothing but a simple cause and effect.

The reason your dog urinates and defecates in the house is typically one or more of the following:

  • A medical condition
  • Lack of house training
  • Anxiety
  • Lack of facilitation

The most simple explanation could be a medical condition, especially if your dog’s house training breaks down all of a sudden, so a visit to the vet is a good start. 

Apart from physical ailments, mental or emotional problems can also play a role. Separation anxiety is commonly behind a loss of bladder or bowel control as are other forms of anxiety, stress and fear. Identify what your dog is distressed about—ideally with the help of a behaviour vet or animal trainer with proven expertise in behaviour—and, most importantly, stop any sort of punitive handling and training.

A rather common cause for house soiling is incomplete house training, so go back to basics. There is no magic bullet to teach your dog not to wee or poo in the house. It comes down to management, supervision and reinforcement.

Then there is the matter of access to the preferred toilet spot. Putting a dog door in for the dog to go out whenever they please seems like a great idea but your dog has to think so too.

Anything new you introduce into your dog’s life is best accompanied by yummy treats so the dog immediately forms a positive association with it. Nevertheless, some dogs may need further help to actually use the dog door without your assistance.

Here are some common factors that can affect your dog’s love or hate of the dog door.

size of the dog door

Make sure your dog can easily fit through the door rather than having to  squeeze their body through. Security may be a concern, in case you have a large dog, although having a large dog may also be a good burglar deterrent. On the other hand, I have had to squeeze my body through a dog door more than once to get entry to a house, so it certainly has its advantages, if you lose your house keys.

design of the dog door

There are a range of designs that can affect your dog’s liking of the door. Hard or soft plastic, see-through or opaque, round or rectangular. Consider how hard your dog has to push or how high they have to lift their paws to get through. Do your research, read reviews or, even better, test different doors before shopping.

location of the dog door

You may not have a lot of choices of where to place the dog door depending on the design of your home. Most commonly, dog doors are installed in backdoors or windows. But where exactly is the door leading to? If it rains, does the dog have to step out into the wet or is the outside space covered? Is it shady on hot summer days or does the pavement heat up so much that it feels like stepping on hot coals? What else could prevent your dog from stepping through the door? Maybe the neighbours kids’ trampoline is right next to the fence and your dog fears the jumping kids. Or maybe the neighbour’s dog goes berserk whenever your dog uses the dog door. Lots to think about.

ease of entry and exit

The location of the door may create additional obstacles for your dog to get in or out. I knew a Schnauzer who refused to step outside through the dog door but had no problem coming in. As it turned out, the step down from the dog door, which was built into the laundry door, was simply too high. The dog had trouble to physically bridge the height and she might have also hurt herself in previous attempts in doing so. Adding a little platform between the door threshold and the courtyard, so the dog could step outside without having to resort to acrobatics, solved the problem in this case.

bad experiences

An unfortunate encounter with the dog door, especially on first use, can easily create dog door dread. For this reason, I highly recommend introducing your dog to the door with a bag of yummy treats. With you on one side of the door and the dog on the other, encourage your dog to step through—initially holding the door open, if necessary—and then pay her with a treat and praise her for her bravery. Repeat this until the dog shows no hesitation when stepping through the door. Lots of positive experiences provide an ideal buffer against possible future mishaps.

If your dog does have a bad experience, such as getting stuck in the door or getting a fright by an external event, say a thunder clap, while going through the door, first consider the previous points and possibly make some changes to the dog door. Next, rebuild your dog’s confidence by teaching her, step by step, that the dog door means wonderful things, i.e. super tasty snacks.

general anxiety

Some dogs are generally afraid of novel things or lack the confidence to explore. The procedure to make your dog use the dog door is the same as after a bad experiences (tasty snacks!) but, if your dog has problems with more than just the dog door, I strongly suggest a consult with a behaviour vet. Living with anxiety is no fun for anyone!

Case Study: Willow, the Worried Whippet

During a recent house-and dog-sit with a pair of Whippets, I helped one of them overcome her dog door anxiety. Apparently, her fear of using the door arose after she was hit in the face by the flap when she tried to follow her brother through the door. The door in question was of round design with a hard-plastic flap, firmly held in place by magnets.

After the incident, Willow would only use the door, if the flap was held open. My initial advice was to temporarily replace the flap with a plastic sheet or fly screen and then gradually reintroduce the hard flap.

A simpler solution may have been to replace the door with a larger version and a soft-plastic flap. However, more assistance is usually required to rebuild confidence after a bad experience.

So, while I had the pleasure to stay with the Whippets, I spent a few minutes daily on behaviour building and counter-conditioning.

Breaking the Behaviour Down Into Manageable Steps

The first step was to get Willow to push the door open just a little with her nose. With me on the other side of the door and a piece of chicken held right at the bottom of the flap, she eventually managed to push—albeit quite awkwardly at first: pushing with her teeth!— and quickly snatch the treat before pulling her head back again.

Next, I had to prevent her from pulling back straight away, so I quickly fed another piece of chicken after the first one and so on. The goal was to get Willow comfortable with the feeling of the dog door resting on her head or neck for a few seconds.

Very quickly this seemed rather easy for Willow, so now was the time to move the food lure out of sight and encourage her verbally to push her head through the door before I reinforced her with a treat. The intention was to break the reliance on the food lure.

The next step was getting a leg through. This turned out to  be a rather interesting looking affair. Despite her small stature and spindly legs, it took Willow some trial and error before she figured out where and how to place her legs. Initially, I offered assistance by holding the door up and then slowly lowering it onto her back.

After managing to get her front legs through and collecting a few pieces of chicken with the flap resting on her back, Willow still tried to escape the scary door with a quick forward hop. It would have been disastrous, if she had pulled back at this stage and rammed the door into her spine, so keeping the forward motion going with treats was essential.  

By moving myself away from the door very gradually and feeding repeatedly as I did so, I eventually managed to convert her panicky hop into a more graceful step-through.

Repetition and Continued Reinforcement

From there I kept repeating a full step-through with lots of verbal encouragement and reinforcement with chicken to grow Willow’s confidence and comfort with the door. The chicken, or other food reinforcement, was now only delivered once she had mastered the entry or exit on her own. I also celebrated each success with plenty of praise.

I had transitioned from food lure directly at the door to reinforcement delivered at a distance from the door after a successful exit or entry. Now I needed her to be able to do it without me.

First, I increased my distance from the door and eventually walked out of sight, still using lots of verbal encouragement. I also used Willow’s brother as a draw card: I would go outside with him, closing the back door behind us and leaving Willow inside. I then made a point of first feeding him outside, then playing with him with lots of hullabaloo, and moving further and further away from the door. Willow, not wanting to be left behind, conquered her dog door dread faster and faster to join the party.

When my house- and dog-sitting time with the Whippets came to an end, Willow was able to go through the dog door without my presence and without encouragement or food offers. She had not yet managed to leave the house at night on her own when nature called, but I left with the confidence that continued practise and repetition, including at night time, would soon have her soar over that final hurdle.

And now I have learned that her humans have decided to install a bigger dog door with a soft flap! :)

How to Get Your Anxious Dog to Play

Being sick is no fun. No matter, if our ailment is of a physical or mental nature, it robs us of having a good life and doing the things we love. Anxiety, phobias or depression can be as debilitating as broken bones or battling a disease. And it’s no different for our dogs.

But, just like us, dogs can benefit greatly from engaging in physical and mental activities, solving puzzles or playing games. It may start as nothing but a temporary relief or a distraction, but it may also grow into a newfound appetite for life. Often, the first step is the hardest, so here is some advice on how to get started with your dog.

Having to Worry About Their Environment Can Make Your Dog Sick and Unhappy

Does your dog shy away when someone tries to touch them, trembles at the vet or groomer or gets upset by noises? Does your dog seem withdrawn or inactive despite being neither physically incapacitated nor very old? Does your dog growl at people or other dogs, or worse?

Dogs who worry about their environment most or all of the time have a stressful life. They often do not have the confidence, drive or energy to engage in playful or investigative behaviours. Instead, they stay where they feel safe and avoid attracting attention. If they are pushed out of their safe environment, they may respond with fearful or aggressive behaviour.

The reasons for this can be multiple. A dog may have been born with a natural shyness or had adverse early life experiences. They may have suffered some form of trauma or been exposed to regular verbal or physical punishment. Or maybe they simply missed out on good socialisation during the critical first few weeks in life.

Although it may seem the easiest option to just leave the dog alone, it usually does nothing to improve their quality of life and their mental health may deteriorate further. Also, the old “leave the dog alone” advice for any dog that shows aggressive behaviour doesn’t really work anymore these days, at least in our modern urban environments. Dogs live in close contact with us and conflict is almost guaranteed since neither dogs nor people are always in a position to get out of each other’s way. So, we better make sure our dogs are happy where they live and look after their mental health as well as their physical health.

Getting Your Anxious Dog to Play Can Add Greatly to Their Quality of Life

Complete care for anxious, fearful and fear-aggressive dogs requires

A great option for enrichment for anxious dogs is capturing and shaping a behaviour. It is a non-invasive—and therefore non-threatening—way to get your dog to do things. The initial behaviour can be as simple as your dog looking at an object near them, let’s say a cardboard box you just put on the ground. If you want to capture this behaviour, immediately praise (or say a cheery “yes!” or use a clicker, if you prefer) and give your dog a tasty treat every time you put the box down and your dog looks at the box.

It will usually only take a few repetitions for the dog to connect the dots: I look at the box –> I get a tasty treat. Soon the dog may not just look at the box, but actually move towards it. After all, isn’t it interesting that looking at a box earns you a treat? There must be something about this particular box. So, let’s check it out!

Eventually, your dog may offer other behaviours such as pawing at the box or biting it, so you reinforce these behaviours and eventually stop reinforcing merely looking at the box. You have shaped your dog’s behaviour from noticing the box to engaging with it. From there you might decide to shape ripping the box apart, so you only reinforce biting and no longer pawing. Next you reinforce vigorous biting and no longer gentle nibbling.

Where you go with this is up to you and your dog. Maybe your dog discovers how much fun it is to rip cardboard boxes apart and doesn’t need food reinforcements anymore or they love finding some tasty morsels you have hidden inside the box. The important thing is that your dog is having fun. And, hopefully, you have fun watching your dog being happy.

Jezz the Anxious Collie Having Fun

The following video shows some scenes of shaping engagement with an object, in this case a carry tray for coffee cups. It started one day when a friend and I had take-away coffee at a park with Jezz, the anxious Collie. There was no particular agenda. Jezz simply had a sniff at the tray when I tossed it on the ground and it went from there. Now she runs at it, picks it up, tosses it into the air, sometimes rips it to pieces and seems to get a genuine kick out of doing so. That was all that mattered. Anxious Jezz having fun!

While this may not seem a remarkable behaviour for dogs without anxiety issues, for dogs like Jezz, who can jump at her own shadow, this is a huge step forward and almost wondrous to watch. Here is how we got there:

A Safe Environment

The first crucial ingredient is the environment: There is a clearing surrounded by natural bushland, set along a creek in suburban Melbourne, where Jezz loves to hang out. In fact, I believe she would happily adopt this place as her permanent home. We frequently see the iconic Kookaburra and other native birdlife and there is even a hive of Australian bees being busy in a tree hollow. It’s a little oasis where Jezz feels safe and comfortable.

Suitable Reinforcement

Next, the reinforcer: I needed food which Jezz loves and wants more of. I mostly used freshly cooked or dehydrated chicken breast and sometimes cheese. Don’t make assumptions about what type of food your dog will work for. Test it by offering a large range of goodies. Most dogs prefer moist treats with meat, fish or cheese to dry kibble.

Observational & Timing Skills

The moment I saw Jezz sniff at the cardboard tray one day, I praised her with a cheery “Yes!” and immediately reached into my pocket for a treat. Jezz knows what reaching into my pocket means: There is a high chance she gets a tasty treat. How does she know this? Because she has experienced it many times over: I reach it into my pocket and out comes a treat.

My timing was crucial here. If I had left even a few seconds pass before reinforcing Jezz with praise and food, she would not have made the connection between her investigation of the tray and the treat delivery.

Being able to watch Jezz approach the tray meant I had to be vigilant and ready to reinforce her with food. If I had missed one or more approaches, I could have missed my chance entirely since without the food reinforcement there would have been no reason for Jezz to continue approaching the tray.

Differential Reinforcement

To develop Jezz’s new found skill further I had to take it up a notch and be more discriminating about which behaviours I reinforced and which ones I ignored or reinforced to a lesser extent (lower value treats or praise only). Differential reinforcement simply means that we reinforce certain behaviours but not others. The “other” behaviours can be anything that the dog may also be interested in doing at the same time, but which doesn’t get us closer to our goal.

In Jezz’s case I simply wanted to encourage any engagement with the tray that looked like play. Grabbing it and running with it or tossing it into the air was great, but she also enjoyed pawing it and chewing pieces off it, so I reinforced that too. Eventually I stopped reinforcing her for merely approaching and sniffing the tray. As a result, she did that less and, more often than not, went straight for the more playful behaviours of grabbing, tossing, running with the tray and—once she got a little tired—dissecting it.

If my goal had been to teach Jezz to pick up the tray and bring it to me, I could have only reinforced her when she put her mouth on the tray but not when she was pawing it. Typically, after a dog has put their mouth or teeth on an object a few times, they start lifting it off the ground occasionally. Once the “new” behaviour, in this case “lift off” happens often enough, the simpler behaviours, in this case “mouthing” are no longer reinforced. Then we wait for the next behaviour to pop out, in this case “taking a few steps with the tray in her mouth” and once this occurs at a sufficient frequency, we no longer reinforce a simple “lift off”. And so on.

When to stop reinforcing simpler behaviours and only reinforce the next closer approaches to whatever end goal you have in mind is a judgement call and, if made too early, can lead to frustration and eventually quitting in the dog. On the other hand, reinforcing the same behaviour for too long, can mean progress is very slow and the dog may even quit because it gets boring!
