I remember reading about this rule and literally feel like I'm checking his collar every time he comes near me (aka several times a day).

Before we got our puppy, I was so determined to learn everything I could before we officially picked him up. Everything about the breeds he's mixed with, looking up articles on AKC, watching videos on Youtube, etc, toy reviews, what kind are good for him, wha kind are bad for him, what kind he needs to have when he's older, etc. I couldn't imagine just going into it blind! lol
