Very interesting about the NC Red Wolf. Jett articulates that nicely.
After the turkey dog Gracie was attacked in VA, I researched coyotes, wolves and coywolfs. We don't have a problem with coyotes attacking hunting dogs in Wisconsin, so that was a surprise to me. Only Gray Wolves will attack dogs, and we can stay away from them (it's mostly bear hounds that get killed). I haven't heard of any instances of the Gray Wolf (Canis lupus) in WI interbreeding with coyotes. But according to the 4 links near the bottom of the page (including a PBS special), the 'Great Lakes Wolf' interbred with coyotes and most of Ontario and the eastern states now have coy-wolves. They're bigger and more aggressive, to attack a GSP like Gracie. WI coyotes would never attack a dog that size. Near the bottom of the page - Researchers confirm existence of the CoyWolf
http://www.turkeydog.org/gracie.htmlBased on the coyotes (and fast dogs) I've seen interacting with turkeys, I think generally turkeys aren't afraid of any kind of dog they can see. They know they can just fly up and be safe. That's why they often don't leave the ground until the dog is close to catching the tail. Experienced coyotes know it's not worth the effort, because the odds are they won't be successful. Same with dogs and wolves. Wildcats could be more successful, but the turkeys main predators are coons, turtles, skunks, possums and crows preying on the eggs. That's my two cents worth.
