@jantan Ah....although I don't think that would have stopped Jarvis. His 'leave it' leaves a lot to be desired. He is very much a food driven pooch. I do love how it looks as though Ripley's really not that bothered, looking into the distance....but the licking of his chops gives himself away :-)
@vfox I have also got a photo of her with her foot on the crisp packet. Having a food driven dog can be a good thing. Ours is only food driven when it comes to stolen food. not really interested otherwise which does make training difficult (well that's my excuse for her behaviour anyway!)
