I could kiss the person who invented the Kong. I've used it for my own dogs during the young years and, now that they're older, as a way to give them something to do while we're away for short periods during the day.

Trainers from across the country will attest to one thing — stuffed Kong toys are a fantastic choice to keep bored and teething canines happy.

Typically, these gems are filled with Easy Cheese (cheese in the aerosol can), peanut butter or canned dog food — and then frozen. The premise is to have the dog work to get the yummy filling out, which takes time.

Dry dog treats are also a favorite stuffing ingredient.

Stuffed Kongs are a great tool in keeping pets sane, but with one caveat: when used regularly, most pet owners find that their pooch has packed on some pounds with the additional caloric intake.

Of course, one should consider cutting back on the amount of food that is given at mealtimes, but honestly, who really does that?

A highly recommended alternative to using the high calorie ingredients can be found in your kitchen: mashed fruit, like bananas, or even applesauce and canned pumpkin.

All of the ingredients are high in fiber and low in calories and contain no fat, so you can feel good about giving your four-legged friends this time tested, fun treat.
