Well, it's like this, little gals can't pull the big gals hair. I only have so much of it you know and those humans don't appreciate it either so it's my job to teach you what's fun and what's not fun for those humans.
I know pups love to bite each other and we don't mind but those humans are sensitive souls so no pulling hair. I know you haven't even nibbled on anyone but I figure as a role model, I would tell you the dos and don'ts of living in human land.
Did you get that?
PS: Having canine moms around to teach is wonderful!
