Had to look it up. No bueno. Growing up we had a wolf/husky/shepherd (over half wolf) and she only lived to be about 10.
AWESOME dog in every way, zero issues. I will have one again once I get a house. I may lean towards a husky though. She ended up getting a "twisted stomach" or something and died within a couple hours. :\
We were hoping to see another NISMO out there, but it's all gravy. Gotta take care of the fam!
