Love this toy
Size: One Size
I buy these all the time for my dog. They’re the easiest for me to throw and the dog loves them. The only reason they don’t get five stars as because the stitching comes out after a couple months. Therefore, I have to continuously buy them. Because of the fact that they are way easier to throw other balls and they’re easy to see also.

Great Toy
Size: One Size
My three year old loves to play fetch and this dog toy was perfect for him. With the bright, signature orange and blue colors, he can easily spot it when I throw it even in the night. He really loves it when it bounces on the ground as he prefers to jump up and get it. The toy has been through a lot and so far he hasn't chewed through it yet as it is very thick for him to get through.

Lasted whole five minutes!
Size: One Size, Size: One Size
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.
