Durable and great value
Color: Paw Print, Size: 8 inches
Best thing we ever bought our Frenchie. It keeps him busy and he gets a great workout in. The tabs make it easier and for me to grab and throw for him. They also allow him to grab them and run with the ball. Only thing he hasn't destroys. Very durable and easy to inflate with enclosed pump.

Lightweight Balls
Color: A.Orange+Blue+Green
lightweight but solid. Unfortunately, I can't bring to dog park for my dog to play with as the larger dogs will destroy them. Not for dogs that chew through everything.
