Predators as these are definitely on the rise and have been for a long time. There are many solutions (proposed)but very few work. You can't shoot, trap, push out or relocate them. Poison works. This is nothing new-blaming the gun again.However keep your pets on a short leash. These wolves will kill anything. Reminds me of a photo of a Pitbull in the local paper that had mangled a 5 year old neighbor. Why is that dog still alive! What ever needs to be done. I have shot Black labs that were chasing a deer. Don.t like to do it, but it has to be done. Across the border, this is a horrible problem.
