Great customer service
The squeakers broke within the first few minutes of my dog playing. But the customer service has been outstanding.

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
