Wonderful outdoor fetch ball!
Theme: 2 Pack, Size: Medium
This medium sized Chuckit is perfect for my 21 lb dog. It's great for outdoor play. I needed to find an alternative to tennis balls because my pup tears up their outside material. With this ball she can easily play fetch and run around. It's easy for her to grab onto and does not impede her breathing. It's seems sturdy and quite flexible. The medium is perfect for her size.

Great Ball for training Labs
Theme: 2 Pack, Size: Medium
This is my 80lb Lab's favorite fetch toy. We workout for 45 min to 2 hr every night that's dry enough (in San Antonio it's standard conditions). When I first saw the ball I almost returned it thinking it'd tear apart very quickly. That proved to not be the case. I've used it nightly for the last 3 weeks or so without any signs of tearing. It has a very good glow for night play. Some may consider it small for a lab, but when playing very aggressive catch it's our ball of choice. We work on catching, chasing, tracking, reflexes.. this ball's perfect for that. The more solid, 3.5 in + balls are simply too much and I'm afraid they could hurt the dog during aggressive play.

Quality is Top notch and the dog Loves them.
Theme: 2 Pack, Size: Medium
Just like every other Chuckit! product I've purchased, the Air Glow Fetch Balls are of great quality and my German Wire Haired pointer loves them. He tends to not immediately bring balls back after retrieving them and prefers to aggressively gnaw them instead which is why I purchase Chuckit balls instead of normal tennis balls and all of them stand up to the abuse. I don't think he's ever chewed any of them apart and they are of high enough quality that we always end up losing or misplacing them before they are destroyed.
