LOL! I think it is great that he can spend time with so many different breeds and ages while still in his socializing stage. The only things that worry me are:
1) He will pick up bad habits of the walker/other dogs
2) He may get used to other commands while walking and get confused when with me
That's why I'm taking time to see how this guy is, what he does and trying to learn about the positive or negative impacts it may have on him first
