Steele layed down.He snuggled closer to his brothers and sister sibes.They were AKC registered pure-bred champion-blood-line Siberian Husky puppies,about 6 weeks old.

Also for what it's worth, Siberian Huskies were not recognized by the AKC until 1930. Assuming you're working within the timeline of the movie, Steele was probably born in the early 1920s. Ironically, it was largely because of the serum run (and Balto's subsequent rise to fame) that the AKC recognized Siberians in the first place.
