Chuckit! Tennis Balls are specially designed for the game of fetch, featuring an extra-thick rubber core for durability and performance that stands out from the rest. Made from natural, high-bounce rubber, these Chuckit! dog toy balls encourage dogs to leap and jump for more stimulating games of fetch. These rubber balls for dogs are durable for long-term use, yet lightweight and buoyant for water-loving pets. The Chuckit! Tennis Ball's soft felt surface is gentle on dogs' mouths for comfortable carrying. The bright orange and blue design of the rubber dog ball grabs dogs' attention in the air and can be easily spotted in tall grass or on water.
