This is Scotch and P.J. There are no rules among these pups. Anything goes in their play. They will stick their opponents whole nose in their mouth and chomp down. Ears, tails, paws, and other things - it's all fair game.
"Grrr, I'm gonna eat your face!"
They are definitely in the teething phase. Having them bite each other is no big deal, but we don't want them thinking the same way about people. We are trying to be vigilant in not letting them gnaw on us, replacing toes and hands with a chew toy instead. It'll take them a little time, they are just puppies after all, but they will get it.
In the mean time, they are very entertaining to watch!
