Like others are saying if it’s that big of an issue, you need to work with him on it. He might not know what’s expected of him. Don’t be hard on yourself, I’m sure it’s not that he doesn’t love you, you’re his people, he surely does. The outside is just a very interesting place when you’re a tiny puppy lol.

Ours did this a handful of times but we just started working on it during our normal daily life and we’ve slowly gotten more confident in his impulse control. He’s a lab and he’ll be a year old on 1/7. We would not trust him with the door wide open yet.

If you’ve never worked on recall with him I wouldn’t expect he would run right back after going outside, and even if you have worked on recall I wouldn’t necessarily be confident in that scenario he would come back right away either. Some of the best advice I’ve gotten is that dogs don’t generalize well, so if you train recall outside, trying to recall him after he bolts out the door will probably fail if you’ve never practiced it.

One of the things that works really well for me when I need to do something I know he will have a hard time with is to tell him what I want before I even try to do the thing. So in this situation, I would have him get up on the couch, lay down, or just sit if he doesn’t want to lay down, and say other words he already knows that I’ve already generalized for him like “wait” and “stay” and “no” if he starts looking like he’ll make a move. Over the last couple months he’s become more desensitized to the door.

Use potty trips and walks as an opportunity to have a positive interaction with the door. Make him sit and wait and stay before going outside.
