Can sled dogs be half wolf?

Answer 1

While modern sled dogs undoubtedly have some wolf ancestry, as do all dogs, there are probably few if any actual hybrids (half wolf, half dog) that are used to pull sleds. A harness dog must look to humans for direction in order to do its job successfully, while a wolf completely disassociates itself from people. Also, wolf hybrids tend to be more aggressive and less submissive than most domestic canines.

Answer 2

All dogs are 100% full-blooded wolf. Dogs are domesticated wolves, just a different subspecies.
