Gracie loves to kill her toys. Maybe once or twice a day she will get in the killer mode and shake the daylights out of one of her toys after she has barked at it and growled for a while. Sometimes she will bring the toy to me so I will make it shake and fight her a bit more. I'll shake it around and squeak it for her and she gets all crazy. She enjoys it and is in no way aggressive with people. She's just a crazy toy killer. She doesn't even tear the toys apart she just likes to scare them I think!
