Very versatile and durable dog toy
This is not a good toy to leave wit big dogs unattended. That being said it is a GREAT dog toy for households that have a variety size of dogs. Our Golden Retriever and 6 pound Pomeranian both play with it. Both retrieve it and occasionally share carrying it back to us. I know it will eventually get destroyed but that is what dog toys are for. Very durable and with the holes, it allows small dogs to pick it up as easily as larger dogs.

Keeps my dog busy
This works great for rolling treats up in fleece and putting them in the ball. The ball material is flexible and durable. This is a fun and engaging activity for when the weather prevents outside fun.

The best dog ball EVER!!!
Our 3 y.o. Mini Australian shepherd destroys every toy that she can. We can’t have any kind of cloth toys, including the heavy duty, triple stitched, fire hose Kong toys. We can’t have rope toys, even the balls. There are many rubber or silicone toys we also can’t have as she destroys them as well. She has 5 of these balls, some for over a year and they are still in GREAT shape. Left in the sun, rain, etc, they just hold up. They also don’t have a lot of surface area to hold slobber so your hand doesn’t get all wet. Heavy enough to still throw a fair distance, but light enough that the dog was fine the few times I’ve accidentally drilled her in the ass. These are the best.

The best dog ball!
I have bought about 8 of these balls now. Mostly because my dog looses his or I’m buying them for my other dog friends. I put a dog bone in it at dinner time and it keeps my dog occupied while I’m eating my dinner. He loves it and so do I! They also have different sizes. We recently got a bigger dog breed so I got the biggest one. He loves it as well! Worth every penny!
