We got these 2 products for Apollo, to give him when we go out. Now, the Kong Biscuit Ball, the biscuits just fall out when he's walking with the toy in his mouth; we use all-natural milk bone shaped treats. So, after 5 mins the treats are all out, and he ignores the toy. The Booda Dogzilla Dumbbell, the opening is small at both ends, so, we though we'd just put some dry food in there, maybe with some peanut butter, but Apollo's tounge is way to big to get any of it out, and he ignores it after a couple tries to get the food out. If you have these products what do you put in them? Any ideas what to put in them to keep him busy?
