That's why the rescue-lady told me....she said that he would have all his power behind him and there would be no way my kids could control him if he walked in a harness. He didn't have good walking manners then, having never really had a family to care for him, and at first he did pull but it really didn't take him long to walk nicely, and now to nap mid-walk! I think it is timing. I need to figure out when he has the most energy during the day, and not probably to expect a very long walk from him. We were initially walking a kilometer out and another back. That might be too long for him?
Reggie is a cutie! Congratulations!! Good luck with the walking stuff, mine is more into the sunbathing in the grass than he is walking they're silly sometimes but they really are the best dogs ever!
