Too small
Much smaller than it appeared to me in the picture. I did not read the length as I should. I would not have bought it if I saw it before purchasing. My 18 month old grandson now has a new toy.

Rottie Approved
Size: Large
My Rottie loves playing with this ball, either alone or with me. The first day she chewed a corner of the handle off (the handle is still usable), but then she figured out what it was for and has a blast with it. She has done no further damage to it, and it is strong enough to play tug. It's her favorite toy.
