While I don't wish to deal with a fox wanting to eat my birds, part of me would love to have a fox fur. I'd probably use it to train my dogs to keep them out since they've never encountered them before (though my dogs are pretty good about dealing with predators anyway).
Have you checked your local shelters/sanctuaries for puppies? There are always loads of young dogs available and they aren't very pricey. Training a young pup to protect the property/flock is something you'd have to do anyway and this way, you save another animal from being euthanized. I checked on PetFinder and it looks like there are loads of great pups that would likely be great flock-protectors if trained correctly. One looked really promising and he's located in Batavia, OH.
That's not a very good photo, haha!
I checked him out!! He is a beaut!! I'm just not sure I want a herding dog. Just need a good guard dog to keep predators out of the yard. If I were looking for that type of dog, I would take him in a heartbeat!! He is so georgous!!
