Fun with a creative twist
Color: Colors May Vary, Size: 5.5 Inch
This would be a toy to get creative with. The quality is there. It’s a nice size it rolls so it’s great as just a bowl that’s slightly rubbery silicone like that the dog can play with and chew a bit. If you have a strong tour, and you believe that they chew everything that you give them eventually they would probably chew it open. Our puppy likes it plays with that as a typical ball. It’s perfect because he can grab it in his mouth and walk around with it lightly and easily. We do take a kitchen towel. Roll it with treats and shove it inside and he’ll have to try and retrieve that that towel with the treats so it kind of gives us a few minutes of peacefulness. You can create so many different fun games with it because you have access to place things inside you know the holes are slightly big so the items inside would have to be of a good size. We have put his his large wishbones inside to allow for him not to have to hold the bone and it gives him some sort of structure as well as if it rolls away, he finds it to be a game so that’s nice. It’s made well. It’s good quality. I like how it’s blue so the dog could see the color and it’s easy to store cause it’s not huge.

Great toy for both inside & outside play!
Color: Pink, Size: 3 Inch, Color: Pink, Size: 3 Inch
My Yorkies love this toy! This is my 3rd purchase of the same type of ball - the small 3" JW Pet HOL-lee ball. I bought one for my first Yorkie, she loved it, so when I got another Yorkie puppy, I bought a 2nd. They play with them so much that they sometimes get left outside. The green one was faded and started to blend it with the grass, so I bought a new one. It's great for a game of fetch, and isneasy to wash. Wish I could select a specific color, as I'd really like a purple one.

Great indoors and out.
Color: Blue, Size: 4.5 Inch
This is a great toy if your dog likes balls. While it's not my dog's favorite (he favors small squeaky animals) it is safe indoors, soft on floor, walls and furniture and something durable for fetching.

Terrific for fetch, would not hold up to unmonitored chewing
Color: Colors May Vary, Size: 5.5 Inch
Fabulous for playing fetch. Young crazy-dog enjoys it! Would not hold up to using as a chew toy - we remove it when not playing with the dog.
