Now that it is summer tis the season for romping with puppies. The little monsters have so much energy so it is a joy to watch them play themselves to exhaustion. These sweet sisters look like they're going to chew each other's legs off but I assure you that they're having a grand time. Still, those needle-like teeth make me cringe, those suckers hurt!
