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.

Gave my dog an allergic reaction

Color: Blue, Size: 4.5 Inch

I have one that has lasted 2 years of hard play, very durable. However, this newest one in the teal color gave my dog an allergic reaction. Her face and eyes swelled up within 1/2 of playing with it. So I threw it out. I have had no issues with the green one that I bought yesterday ago.
