Sam is so nice to Luke. He teaches Luke how to play tug, how to chase and fetch. What does he get in return? Luke hangs from Sams’s ears, bites his neck, chomps on his legs and nips his butt. Sam is exacting his revenge in an ostensibly innocuous manner….nonchalantly chewing away on Luke’s bully stick and appearing to be unaware that he is laying across Luke’s favorite squeaky toy. Oh, clever. clever Sam! That’s the way to make this young interloper go mad!
