A "friend" of mine came over for a barbecue last summer when Mackensie was only 3 months old. She jumped up on her, and this "friend" grabbed her front paws and squeezed her hard until she yelped! I freaked and said, don't ever do anything to hurt my dog again, or you will not ever be invited to my home in the future. She looked at me like I was the stupid one and said "are you kidding me? She's a dog, I am a human, she has to learn not to ever jump up!, That's the way you're supposed to teach them." Apparently she did this to "teach" her dog, and it worked...
