KONG Tennis Friends, a fun new puzzle product, blends two favorite items for dogs: the tennis ball and the squeaker toy. The solid tennis ball is loaded into the body of the squeaker toy, which does not squeak, providing an exciting obstacle for dogs to extract. Alternatively, the Tennis Pals' unpredictable bounce can be used for fun fetching games.
The material is sturdy - good as it doesn't get chewed up easily. Interactive as it's bouncy! very entertaining toy to keep them going. :)
