I had a dog when I was a boy. He was half basset hound and half dinosaur. 85 lbs. of dog built real low to the ground. A canine battering ram. Squirrel was one of his favorite take-out meals.
I had a husky dog that would instantly go for the kill if any squirrel came within leaping distance. Saw him jump six feet straight up, after the squirrel jumped, and pick that squirrel right out of the air. The dog would jump up on top of the car to take a nap or keep a lookout for squirrels. I think it was a dog; too small for a wolf.
