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.

These are NOT meant for regular play like the other reviews seem to think.
First things first, ignore 90% of these reviews. The reviews saying these balls didn’t last very long clearly don’t know what they’re meant for. These are not “drop and play” kinds of toys. They’re meant to be used as reward toys. Meaning they get used during training sessions for a quick game of tug to reward the dog for good behavior. These are NOT meant for unsupervised play, and not meant for dogs who don’t have reliable recall or drop/Aus commands.
That being said, my dog is 95 pounds and stands 29” at the shoulder. She’s a big girl who plays rough. Immediately after opening the package, we did a quick training session with these reward toys. They held up EXTREMELY well. They are made of rubber which means she doesn’t shred them in one short game of tug unlike some of the foam reward toys you will come across. I did have to tighten the knot below the ball before using them, but that’s to be expected with any rope style toy.
If your dog does not have a reliable drop command and they are any larger than maybe 25lbs, I would not suggest using the smaller ball. If Nikita didn’t have a reliable drop command, it would be incredibly easy for her to wind up choking on the smaller ball. Even the large ball is pushing it on choking hazard size for a large dog, but again, reliable drop commands are important.
