The Kong company has expanded its product line in recent years but nothing beats the Kong Classic for chewers – until now. The KONG® Blue is especially tough and is available through veterinarians. It is made of an all natural, puncture-resistant, radiopaque rubber. It’s 25 percent stronger than the KONG® Classic. The product is said to help relieve boredom, stress, anxiety, and aids in post-op recovery. Made in the USA.
