Just stuff with kibble or treats and watch the fun begin. The Kong Stuff-a-ball will keep dogs contentedly busy for long periods of time. The extra large Stuff-a-Ball is 4.25" in diameter.
The patented dental ridges of the Kong Stuff-a-ball will effectively clean teeth and gums. For an extra cleaning use dog toothpaste or Kong Stuff'n Pastes inside the grooves.
Great when used with a variety of Kong stuff'n treats.
