I received this last night and did a cute "unwrapping" this morning for my dog, who was thrilled to get new balls. Unfortunately, the excitement was short-lived. I know the description says this isn't a chew toy or for aggressive chewers, but lasting only five minutes is ridiculous. You can see in my photo that it ripped from a single bite while my pup was just pulling the ball. I thought that was exactly what this toy was designed for!

Super fun!

Size: One Size

Our GSD loves this toy whether playing with it by himself or with us - he grabs the rope and flings it then chases it…it’s become his favorite toy!

Dog loves it, but it comes apart pretty quick.

Size: One Size

The dog loved chasing it and playing tug-of-war, but it lasted less than 30 days. If the outer rubber portion of cover was thicker, or all canvas material, it would probably last for a few months of rough play. May buy again if I can't find something similar to try.

One Tough Ball!

Color: Blue

Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

My puppy’s favorite

Color: Orange

Great quality and built to last. My dog really enjoys playing with it and stays entertained for quite a while. The material is strong yet safe, and the included drawstring bag is a convenient extra for easy storage. Is colorful and my become my puppy’s favorite.
