Pawsome product!
Color: Glow in the dark I, Size: Medium
Pawsome for our doggos! We have bought 5 because the puppy chewed the tags off. Our dogs are border / aussie mix and love the challenge of these balls. We named them "Wilson" because they treat them like their best friend.

My Monster Dogs destroyed these balls
Color: Glow in the dark II, Size: Large
I was so excited to get two of these balls for my doodle puppies to have to play with . THEY DESTROYED THEM IN ALL OF TEN MINUTES. I don't believe that there was anything wrong with the balls. They were beautiful, high quality balls. Just not durable enough for my doodles.

Sturdy, well made, puppy & senior dog approved
Color: Glow in the dark I, Size: Medium
Pet approved !!!! Our puppy immediately grabbed it by the straps and took off!! It is well made and has handled some serious chewing in the last 24 hours. We love the glow in the dark because puppy playtime does not stop when it gets dark out!! It came with a pump and was very easy to assemble and inflate. This toy would be great for a pet owner that struggles with grasp & grip strength, the straps are absolutely genius.
