I have just given Mia a giant kong stuffed with carrot slices, chunks of swede and few bits of broken up bonio held together with dabs of peanut butter. It took her less than a minute to get it all out and she has now turned into a Tasmanian Devil. She was racing around like a whirling dervish doing a high pitched, staccato bark, tossing everything she could find into the air, ripping cushions off the sofa and duvets off beds and growling when I tried to stop her. She only stopped when I shouted at her and I have never done that before. She is now half calm but still seems to be able to do anything but mischief. Is she just really happy......or had a bad reaction to her first taste of peanut butter?
