We call these "Deb's" used tennis balls because Liana's mom, "Deb" is a fanatical tennis player and would get rid of her old, worn out tennis balls by giving them to our dogs. Considering we go through a fair amount of balls with 4 Labrador Retrievers, it was a godsend!
So when we started the store, we thought if we could coordinate the local tennis players to donate their worn out tennis balls with the dog owners in the area who wanted them, we would have a great way to support our local animal charities. And so far it has been a resounding success!
