Dogs love them
Color: Skull Print, Size: 6 inches
I ordered 3 of these well made balls with pull strips for my 2 Aussys. easy to inflate. Dogs have great fun. Sure beats a simple ball.

Belgian Malinois
Color: Skull Print, Size: 6 inches, Color: Skull Print, Size: 6 inches
Any toy that last over 2 days with a Belgian deserves 5 stars.
I purchased this for my pup's 2nd birthday. She loves it. Within in 24hrs all the tabs were chewed off but the ball itself is still holding up. She plays volleyball with it, catch, Chase, and chews on it. It is going on a month and it is still around. Thank you. It is difficult to find a toy that lasts with a Belgian and they are hyper dogs that need toys.

A MUST for busy dogs!!
Color: Green, Size: Medium
The tags are a hit! My border collie entertains herself with this ball. The longer black tag is PERFECT for her to grasp it and fling it in the air.

He loves his new ball
Color: Paw Print, Size: 8 inches
My German Shepherd loves it. The only issue we had is that he managed to tear the black handle off within 5 minutes, so we just ended up cutting it completely off. Other than that he loves it.
