The basic principle of Kong stuffing ensures that some food comes out quickly and easily to instantly reward your puppy for initially contacting her chew toy; bits of food come out over a long period of time to periodically reward your puppy for continuing to chew; and some of the best bits never come out, so your puppy never loses interest. Squish a small piece of freeze-dried liver in the small hole in the tip of the Kong so your puppy will never be able to get it out. Smear a little honey around the inside of the Kong, fill it up with kibble and then block the big hole with crossed dog biscuits.
There are numerous creative variations on basic Kong stuffing. One of my favorite recipes comprises moistening your puppy's kibble, spooning it into the Kong and then putting it in the freezer overnight
