Kongs are made of rubber and are hollow inside. They come in all shapes and sizes but the original shape and most popular is the hive-like design. They have the ability to bounce although we don't use them for that purpose.

When Molly and Jack were puppies we bought Kong Stuf 'n Paste which is a canned (like a whipped cream dispenser) that contains whipped peanut butter or liver flavored paste. Although they liked the paste for awhile, we decided it was far easier and probably more nutritional to use real peanut butter and cream cheese in the hollow Kong.

Using the Kong with stuffed goodies is ONLY for special times. The Cairns know that when they get peanut butter in a Kong they have done something really, really good. When they get cream cheese in a Kong, they know they are going to spend some time in their crates. They don't care. They love the stuffed Kongs and since the use of them with stuffed goodies is not over-used, they look forward to these special times.

Other treats can be stuffed in the Kongs and are fun for puppies to work with when they are bored. Entertaining a Cairn Terrier non-stop can be work, but tightly packing a Kong with pieces of broken dog biscuits can be a fun task for a puppy. We used this technique with Molly and Jack on occasion when they were young pups and when us ole human adults needed a break for the youngins' high energy.
