Now THAT looks like my kinda party!
Dog Party Piñata Filled With Tennis Balls

To celebrate his birthday, Moose the chocolate lab had some friends over to the park to bark and chase each other and his owner Hannah Helsel made him a pinata that opens with the pull of a dangling tennis ball, and is filled with even MORE tennis balls. Dogs love those things! Mine like chewing all the green hair off the outside so I can see it their poop later. Fun!
