Kongs are great for puppys when teething and stops adult dogs getting bored when you are out. What you need to do is put some small biscuits in the bottom then get some cheap cat or dog food or some cheap sandwich paste, then put it in the kong and push it down hard, put some more small biscuits in the kong and fill to the top with your filling, then the key is to freeze it and this will keep your dog happy for a long time, its best to get 2,so you can keep 1 in the freezer as a spare.
