Favorite ball!
My dog absolutely loves this ball. I have a 11 pound mini golden doodle for reference. It is super durable and easy to clean. It is easy for her to get her teeth around and is one thing she has not chewed up.

Sturdy and long lasting.
These balls are a favorite of my Sheltie! She loves to chase after them and catch them in the air. My dog is not a chewer so I can't say how they hold up under aggressive circumstances! They do last a long time .

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!
