How to Train Your Dog to Use a Doggy Door

Start with a Helper and Treats

The easiest way to teach your dog to use a doggy door is with a helper and your dog’s favorite treats. Clip a six-foot leash to your dog’s collar, run the end through the door, and have your helper stand outside holding the flap open. Stand on the inside, holding the leash end, and call your dog through with a treat. Most dogs will run through if they can see you and the reward. If hesitant, guide them gently with the treat near their snout. Repeat this process several times in both directions until your dog moves through smoothly.

Gradually Reduce the Opening Size

Once your dog is comfortable going through with the flap fully open, lower it to about 50% open. This creates a smaller opening, encouraging your dog to trust the flap. Call your dog through again, and if they hesitate, open the flap slightly more. Use treats to lure them forward. As they pass through, have your helper gently touch their back with the flap—this helps them learn it’s soft and movable. Repeat this in both directions until your dog no longer hesitates.

Teach the Dog to Push Through the Flap

The final step is teaching your dog to push through the flap. Have your helper lift just the corner of the door so your dog can see through a small gap. Position a treat at the open corner to lure them. As your dog pushes through, they’ll feel the flap move—this is the moment of clarity. Most dogs understand immediately that the door is soft and can be controlled. Repeat this a few times, gradually opening the flap more until your dog confidently goes through on their own.

Special Tips for Small or Brachycephalic Breeds

For small dogs or brachycephalic breeds (like Bulldogs or Pugs), the training needs extra care. These dogs may have trouble pushing the flap without risking injury to their eyes. Instead, have your helper hold the leash on the same side as your dog. This allows them to control the pace and guide your dog slowly through, helping them learn to adjust their head position and push gently. This method prevents sudden movements and builds confidence safely.

Build a Safe, Polite Routine

Once your dog uses the door independently, reinforce good behavior. Train them to wait at the door instead of rushing through. For example, teach them to back away and sit when you approach the door. Then, open it, go through, toss a treat, and close it. This teaches patience and safety. You can also train them to sit on the other side until released. This prevents accidents and helps them learn to use the door responsibly.
