Joe, the founder of KONG, has a pet dog, Fritz, who loves to gnaw on rocks and branches. By chance, Joe threw the rubber parts of the shock absorber to Fritz to play with while repairing his car, and unexpectedly, Fritz's attention immediately shifted from the stones on the side of the road to the rubber parts that produced irregular bounces. This serendipitous discovery inspired Joe to start a business with rubber pet toys.
 
KONG is the world's No. 1 seller in the field of stuffed nibbling toys, and KONG also won the first place in the "Best Dog Toys" ranking bestreview.com the authoritative review website. In the e-commerce market, KONG is firmly in the first place among Best Sellers in many pet categories on Amazon, and its influence is all over the world.
 
KONG mainly sells solitary pet toys, but unlike other brands, KONG's toys are mainly shaped with the iconic gourd shape, with a good elastic rubber material, which can produce irregular bounces, which can stimulate the dog's interest more than conventional spherical toys.
 
The gourd series is a hot-selling classic of KONG, in addition to having the characteristics of irregular bounce, it is also classified according to the age of the pet, the size and the bite force, which is quite professional. The gourd series is divided into light blue (pink), red, purple, and black colors, which are suitable for puppies, adult dogs, old dogs, and strong bite dogs. KONG's other series of products are also basically classified according to this color, which can help pet owners find more suitable toys accurately.
 
The appeal of ordinary toys to pets is often temporary, while leaky toys that can be filled with food can significantly improve playability. The gourd series is designed with a circular food leakage at the top and bottom of the toy, and the dog needs to roll the toy with its paws and head to get food. However, the size of KONG's leakage mouth cannot be adjusted, so the difficulty of the game can only be increased in the form of frozen toys, which is not very convenient in practice.
 
In order to make up for the lack of difficulty adjustment in the gourd series, KONG has also launched difficulty upgrades such as WOBBLE and GENIUS LEO. WOBBLE IS A TUMBLER TOY WITH A LEAKY MOUTH AT THE WAIST OF THE TOY, WHILE GENIUS LEO HAS DESIGNED THE LEAKY MOUTH INTO AN "X" SHAPE OF DIFFERENT SIZES, WHICH MAKES THE GAME MORE DIFFICULT. If the dog in the family can already easily get the snacks in the gourd series of toys, the owner can consider buying these two upgraded versions.
 
KONG's pet toys are currently made of natural rubber and are FDA-certified for safety. In addition to solitary toys, there are also interactive toys such as frisbees, tug-of-war, and balls, and the unit price is generally more than 100 yuan.
