The traditional Kong is a hollow, hard rubber toy, shaped something like the top of a soft ice cream cone. By smearing a bit of wet dog food, or something else tasty, inside the toy you make it a delicious project that your puppy will probably spend a long time working on. After he's done trying to lick every last bit out of this toy, you can run the Kong through the dishwasher or give it a good scrub. Placing the Kong in the freezer also makes a great soothing chew for teething.
These tend to be a love'em or leave'em chew toy – either a puppy is wild about them or he doesn't know what to do with them. Nylon bones come in a wide range of sizes. Make sure you buy an appropriate size for your puppy or buy one your pup can grow into. These bones also come in different flavours such as, chicken and liver. If this bone puzzles your pup at first, try smearing a small amount of something delicious on it to get him started. Throw nylon bones out when they wear down and get small enough for your puppy to swallow – though that normally takes a long time.
Treat dispensers are not chew toys, they are hollow toys that you can fill with treats. As your pup rolls the dispenser around, a treat sporadically falls out. This random reward is irresistible to some pups that will play with these toys for quite a long time. Others seem to give up quickly. Starting out with the setting that releases the most treats usually gets the ball rolling so to speak. Once a pup learns the game, he will generally stick with it for a while. Keep in mind that these toys can be noisy on hardwood floors.
If you save these toys for special occasions they will remain attractive to your pup and serve their higher purpose – as puppy pacifiers for emergency use by the loving, but truly tired puppy owner.
