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.

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.

The best gift for new dog owners
Color: Blue, Size: 4.5 Inch
This has been my mom's go-to toy to gift to friends and family when they get a new dog. I just followed suit and bought one as a gift for my friend's Newfoundland puppy.
Versatile, can be used as a ball or tug of war toy, and can buy a bigger size for a puppy to grow into because they can still grab it by the holes, unlike other balls and toys that are just too big to get their mouth around
