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.

absolutely must buy perfect for dogs. I have a large black lab and he has had so much fun with us.
Size: Large Size 3, Color: White-Blue
I have to say that my dog would be considered an aggressive tower. However, this ball has stayed intact. I love that it comes with the pump. It’s extremely functional very soft for catching can be cleaned. Very easy easy the quality is exceptional. Very functional does have a bounce. I can say he has had so much fun with this since it’s getting it for his birthday on 11/11 I highly recommend this product and would definitely buy again.

Perfect for keep-away
Size: Large Size 3, Color: Red-Blue
I purchased one of these for my pup and he has a ball throwing it up in the air and chasing it. Handy for something they can play with alone.
