dog ball
Color: Blue
This ball is perfect for keeping my dog ​​active and entertained. It's made of strong, durable material, ideal for games of fetch. It doesn't break easily and is light enough for him to carry in his mouth without any problem.

Fun but not for rough play.
Color: Orange
The ball contented our “golden” Jaxson for about 15 minutes. He then thought it was a regular ball and it’s just a little delicate for a big dog. I just wrote it off as a loss. Great idea but should be more durable.

Great product
Style: Sport, Size: Large
This is a lifesaver. My lab will chase the ball all day and this saves the arms and shoulders. A little bit of a learning curve to use but I would definitely recommend
