Their eyes are wide open, and they've found their voices. They bark. They whine. They growl as they awkwardly wrestle and try to pounce. They haven't much finesse yet, but they're cute while they practice playing. They still spend a lot of time sleeping, too.
Notice how intensely both pups are focussed on the bit of black puppy tail -- you can't see it in the photo, but this black one, like all the others has a white tip at the end of his tail. Neither of the sable pups caught the tail, though they sure tried hard enough before Mama Dinah came in and distracted them with the prospect of food. Nothing gets between these pups and a meal.
