Was Steele part wolf? Here's some clues if he was or not:

1. Balto was a hybrid and hybrids are supossed to be taller then average sled dogs, huskies, and other dogs husky- sized and for the most part, Balto is bigger or as big as most of the sled dogs in the  movie except for Steele, who is the biggest sled dog in the movie.

2. Balto falls off the cliff and climbs back up after realizing he's part wolf (and hinting that only a wolf could survive the fall and be okay). Steele climbs back up faster then Balto and gets home before him!

3. Boris tells Balto that only a wolf could survive the journey alone and Balto barley survives it when he has Steele's team and the white wolf for back up. Yet, after falling off a cliff, Steele somehow gets back in front of Balto (before Balto falls off the cliff) and makes it back to Nome all by himself.
