as for me it's really hard to keep training your dog when you see no result 
Edit: Thanks for the great recommendations! I have transitioned to High Value treats and actually shortened the walks (so he doesn't get overly tired). He's doing better. I need to teach him the difference between potty breaks and walks. We are working on that.My puppy has been really good on his lease training, but has started pulling back and sits there staring at me when I try to get him to walk along with me. He acts like he is exhibiting signs of dominance. He's a little guy so I can just pick him up. How can I continue to move progress of leash walking along without him being stubborn?
