Puppy Paws, the first YouTube episode on the lives of Denali National Park's new litter of sled dogs.

This summer, Denali National Park's kennel is opening its virtual doors to something special -- the birth, rearing and training of a its annual litter of sled dog puppies.

Kennel workers will do this through YouTube videos, a live webcam as well as the attached pictures taken by Jamie Dittmar of the National Park Service.

According to an email from the park's kennels manager, Jen Raffaeli, each year the kennel breeds one litter of puppies to replace retiring sled dogs. This year's litter of three puppies was born on May 3. Park sled dog Sultana was bred with musher Brent Sass' lead dog, Silver. There are two females and one male.

The pups -- Little Annie, Polly Wonder and Lucky Strike -- were named after historic mining claims in the Kantishna area. Raffaeli says everyone visiting the park is welcome to visit the pups in the kennels.

The Dog Blog will be following the adventure with periodic links to new videos and also with a standing link to The Puppycam, a webcam with a live video feed and some still shots starting Tuesday.
