Training Your Dog to Use a Dog Door

When I talk with other dog owners, the same story comes up again and again: someone installs a shiny new dog door, excited for the freedom it’ll bring, only to discover their pup just stares at it — or worse, scratches at the wall next to it. I’ve been there too.

The good news? Dogs aren’t born knowing what a flap is, but with a little patience and the right approach, you can train them to use it without stress.

Here’s how.

Training Your Dog to Use a Dog Door

1. Start With Familiarization

Before you even encourage them through, let your dog sniff, paw, and get used to the door. Hold the flap open so they can see the outside and realize it’s not a wall.

2. Use Treats and Praise as Motivation

Dogs learn best when the reward is immediate.

• Stand on the other side of the door with a treat.

• Call your dog through while holding the flap open.

• Shower them with praise when they step through.

I once had a friend whose terrier wouldn’t budge until we used hot dog slices instead of kibble. Moral of the story: the right bribe matters.

3. Teach One Direction at a Time

Some dogs are fine going out but hesitant coming back in. Break it down:

• Practice exiting first.

• Once they’re confident, switch sides and practice entering.

• Reassure them with a calm tone and repeat as needed.

4. Gradually Lower the Flap

At first, keep the flap propped open. Then:

• Lower it halfway so they gently push through.

• Eventually let it rest fully closed.

• Always reward after success.

This step-by-step desensitizes them so the flap becomes normal.

5. Keep Sessions Short and Positive

Five minutes a couple times a day is better than one frustrating marathon session. End on a win, even if it’s just them poking their head through.

Common Mistakes to Avoid

• Forcing your dog through the flap (creates fear).

• Skipping rewards (they won’t see the point).

• Expecting instant success — some dogs need days, not minutes.

Closing Thoughts

A dog door is meant to give your pup freedom, not stress. With patience and positive reinforcement, most dogs pick it up quickly. Before long, you’ll hear the gentle flap swinging and realize your dog’s mastered independence.
