I got the book 'Mine', and it looks good, but I can't find "directions" for our specific problem. Spanky only guards stolen food items. He doesn't guard toys, his food, food that hits the floor when we're around..........but if he steals a food item that got left out at his level, he will growl rather menacingly sometimes when we go to get it. The obvious answer is to not leave food lying around. Next, is not to challenge him. I don't. I will trade with him. It is just that once in awhile, visiting relatives, etc., have found him with something, for example, a potato chip bag, that he's tearing up to get the crumbs, and he's growled when they go to get it away so he doesn't make a mess. Is there anything we can do, perhaps based on the exercises in 'Mine' to work on this particular type of guarding besides keeping everything put away to prevent the stealing in the first place? 'Mine' has nice specific steps to work on guarding food bowl, toys, bones, etc., but I couldn't figure out how to implement for guarding stolen food. Any ideas?
