Nowadays, dogs no longer have to “work” for their food. For many of your pets, hunting is now a game that poses mental and physical challenges. Gnawing up the meat from the bones of prey did not just fight hunger, it also exercised the chewing muscles and kept teeth clean. With the KONG Stuff-A-Ball you can offer your dog just this effect. Boredom and negative behaviour is prevented with this great toy. The shape of the KONG Stuff-A-Ball makes it roll and bounce in unpredictable ways. This awakens many dog’s hunting instincts and they will start to chase, catch and chew this great toy. The KONG Stuff-A-Ball can be filled with snacks or ordinary food - reward your dog for the “hard work” and double the fun!
