Keeps the puppy entertained for hours
Size: X-Large(8")
My dog loves this. I've had to buy two because my dog destroyed the first one but there's only so much you can do with a 5 month old german shepard.

Not durable and lasted a week
Size: X-Large(8")
Had it a week and it popped. The durability is not good! It’s not chew resistant, the value for the money is poor! My dogs enjoyed it for the week it lasted it was a good size , however extremely disappointed!

Fun dog toy
Size: Medium(6")
Great ball, easy to use, sturdy toy, and fun toy that dogs love. Only a 4 star as I wish it was a little bit bigger and with more handles.

Nice ball w/straps to grab for ur dog to carry the ball.
Size: Medium(6")
She’s afraid of SO many things. Gotta give her more time. From a hoarding group…so, no socializing. Time will tell. Very nice ball w/ tough straps to grab hold of & carry it.
