We see them occasionally here, but we hear them quite a bit. They killed an adult Labrador retriever and gutted it a year or so ago. Alone, they can be tough, but in a pack they are nearly indestructible when they want to attack something. Besides the obvious deer, they get to sheep, and an occasional calf around here. But those stories don't make the news compared to when they grab a dog or cat and run off with it.
