Thanks for the suggestions. I have tried gloves, dropping treats, all kinds of treats, etc. I think I might try the Lickety Stik. I understand the Premack Principle but the problem is applying it on his first walk of the morning. He has to get outside to pee quickly so I think he was getting the idea that it’s okay to pull sometimes so was getting confused. In a couple of weeks we’re going to be able to fence in a small area outside the back door. So my plan is to take him there off leash for his morning potty break, then only let him go to the dog run if he walks nicely. If he continues to pull he goes back inside. This way I can reinforce the proper behavior every time he’s on the leash so hopefully he’ll figure it out quickly.
