My husky mix has developed a unique stalking style. We have a bird feeder in the far back corner of the fenced yard where squirrels, birds and field mice come for dinner. Hunter (an appropriate name someone else gave him) will ease out of the doggy door, ever so slowly so as to not make noise. Then he will pad silently, slowly across the path, so innocently that even the feeding birds continue about their business. He doesn't care about birds. He wants sqirrels, or rats. The birds know he isn't hunting them. When he gets near the feeder, he does a sort of 'pounce' where he jumps straight up and lands with all 4 meaty paws and 75 pounds of weight on the area where the seeds fall. He doesn't usually get a squirrel, they're too smart and aware, but he has pinned dozens of rats that way.
