Fabulous play!
Size: Drop Ball
It is small for my 1 yr old girl boxer... my bad for not reading the product size details. The tug rope is great, but my rough boxer loved it too much and couldn't be trusted with it after much play. This toy opened the door for my purchasing tougher rope pull toys from the same brand.

Short lived, my 6 month mini schnauzer took apart the ball first thing and it started to fall apart from there all within a day.

Shreds easily
Size: Drop Ball
I wanted a tug toy for me to play with my puppy and saw this would be perfect. Within 2 days my puppy had it shredded. It is a great tug toy for your average chewers but not for an aggressive chewer.
