Medium Kong Extreme 3.5"
The Chase is on... When a Kong Toy hits the ground, dogs instinctively "GO FOR IT!" The Jawrobics Work Out... The chase promotes a healthy, stimulating "nose-to-tail" workout of every muscle and reflex. After the Catch... The all-rewarding chew begins; and goes on and on. Kong's strong, thick, flexible walls keep springing back for more. It satisfies a dog's natural need to chew and also cleans teeth and conditions gums. (Extreme Kong, Medium)
