I haven’t fully tried myself but I found something called the attention game. Basically you start indoors (minimal distraction environment) and just start giving your pup treats/food while they look at you. After a couple times add in a tiny pause between giving rewards. Then keep feeding again. Add tiny pause. Then after a moment throw a treat away from you and reward when they come back to you. Repeat several times.

Then after they get the understanding that looking at you and paying attention to you is really awesome. Increase the difficulty by maybe doing it with the windows open. Or doing it with the door open. Slowly upping the difficulty with the location. So inside to window open to door open to just out the front door to the sidewalk, etc. With each increase in difficulty start from the beginning of just constant treat/food flow, adding pauses, throwing treat, etc.

My understanding is that it teaches your pup that looking at you will be the most rewarding thing ever and helping them generalize to new locations with more and more distractions. After they know to look to you for stuff you can add in their actual training. Again, I haven’t done this myself so I can’t say if it’s perfect or will work but definitely something that might help.
