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.

Great for our Lab!
Style: Classic + 2pk Ball, Size: 26in
Our Lab loves playing fetch and this is a great product to assist doing that. Great for open field, football-soccer fields, just any large open space. Another great use is scooping the ball up with ease.
