I have recently bought a new pup that I am really excited about. I have been following Duck Dog Basics with my older dog with great results. My only question is that when I tried to socialize the pup with some other pups about his same age they played great until my pup started to get a little more aggressive with the other pups which in turned into a pup fight. I let it go for a sec thinking that they would quit, which I could tell after about 30-45 seconds that they weren't. This is the first lab pup that I have owned and I really want to be able to take him anywhere I go without worrying that he is gonna fight everything. Chris Akin really doesn't address this issue, but I think that I may be blowing this out of the water and over thinking it. How do I nip this in the butt now so it is not a problem later?
