I love these and I do PE at the elementary school. These colors make things a lot easier to teach kids about their skills.

Make your doggos’ dreams come true
Color: Multicolor
Perfect gift for a dog who LOVES tennis balls. Finn a golden retriever was in heaven! We sent this big box of tennis balls to him and his family dumped them all out for him! The balls are the perfect size for chasing and general play. They seem durable, at least as durable as they can be when confronted by teeth. They are a great value. We put them on subscription so he can have an endless supply.
