"What happens, finally, is you turn a corner – this one being deep in New Hampshire at the bottom of a frost-heaved dirt road over a Western ridge. There is a sign there, crude letters on simple planks. "Loki Clan Wolf Refuge," it says. And you turn that corner and then you see one. You see a wolf. Her name, you learn later, is Wayah. You're here to meet the man who saved her."..more big puppies there

I found this small website about the Loki Clan sanctuary, has a few more pictures and links for donations, etc. This guy must go through a lot of burger and chicken! Check the size of the wolfdogs next to him.

When I was in junior high, a good friend of mine had a neighbor next door that raced sled dogs, and he had some wolves he used for breeding into his dogs, so I guess those were wolfdogs, too. Again, large guys. The pure wolves though were kept in a cage when they weren't out that certainly appeared to be twice as strong as the dog's cages judging by the steel size. I am really guessing here, but probably closer than not to 200 lbs apiece. I know they were a lot bigger than me at the time. They'd stare at you and you can tell they were at least half contemplating lunch-lunch thoughts ;) heh
