Where is the squeak
Color: Mixed Color C, Size: Small (Pack of 4)
They seem durable but I needed them to squeak and in order to get a noise out of them you have to really put pressure on the ball...I need a good squeaker for recall w my dog

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.
