If you explain you need her dog for important research

You try not to act too strung out as you tell the lady you need her dog for important research that will someday cure diabetes. But then you hear the clacking of canine claws on the tiles of the kitchen. You try to speak louder to cover the sound. The lady came over to ask if you have any spare sugar for a pie she plans to bake. You step into the doorway of the kitchen and spread your feet out trying to block the dog's progress. A miserable rotten dog head peers at the old lady from around the corner. He makes a sick dry yap. The thing is sucked almost dry, you thought it was dead. But it crawled from the fury pile. The dog still has that electrical cord hanging from its spine being as its your most recent victims. The lady begins back peddling towards the door saying she is calling the human society on you. The dog chooses that moment to die. It falls to the floor unmoving.
