Puppy proof!
Size: Large Size 3, Color: White-Blue
Purchased the blue ball. Puppy loves to carry and shake the ball with the strapes in her mouth. Lots of bite marks but hasnt popped it. We bought 2. She plays in her fenced in yard with them. Fun to throw and kick around.

Great Toy For Playful Pup
Size: Medium Size 2, Color: White-Blue
We have purchased three of these! Our dog is obsessed with them and they keep her very entertained. The strap is a great tool for her to easily pick up the ball.

I have a medium size dog 25lbs. The tabs all came off within 4 days & deflated/punctured in the same amount of time
this ball is not as sturdy as they say.

Quality product but sold on Amazon cheaper with different seller.
Size: Medium Size 2, Color: White-Blue
The size is the reason for the missing star. Made of good quality but found cheaper from another buyer. My 9month Cane Corso hasn't destroyed it yet and enjoys playing keep away with the other dogs.
