stacwase, that is wonderful that wolf populations are returning in your area. I have heard that too. It's sad that people are so uneducated when it comes to wolves. They are shy and I am surprised that you have seen them. What a blessing

Wolves are more scared of humans than the other way around! I'm surprised that they would resort to eating, killing pets because wolves do not tend to like non-natural diet (ungulates, rats, mice, rabbits, grains). Unless there is not enough of their wild prey available, they will resort to pets and domisticated livestock. Coyotes tend to be a little more open to human contact because they have had to learn to survive in the overpopulation of people into their natural habitat.
When I was in college, I worked at Wolf Park in Indiana. It was so wonderful and I really learned a lot. There are lots of pictures there of the wolves if anyone is interested in seeing them.

I also have tons of pictures of them from my years there.
