This is my dog’s absolute favorite. I bought this one as a replacement. Finally after years of use one of the tiny ribs gave way. Ball is still completely useable, but got another. She chomps down on it constantly, tears at it, shakes it in her mouth. It is extremely durable. One of the great things about this ball is how ‘soft’ it is. Meaning the way it’s constructed makes it have a lot of give. The texture of the ball itself is firm, but the amount of ‘airiness’ means you can throw it inside your home, against walls, furniture, etc without worrying about any damage. Great toy inside and outside. Highly recommended ball toy. They make all different sizes. My dog is 25 lbs and loves both the 3” and the mini. The mini ones are the same size as mini tennis balls..problem is she would destroy a mini tennis ball within a day of getting one. She has had the mini Hol-ee Roller for years. Super durable.

I have a toy dog and she really loves this

Size: Small

however her mouth is very small and she had a difficult time gripping the ball. so I took a pair of scissors and cut out a section to make a bigger hole for her to get her little mouth through and now she has a lot of fun picking it up and playing with it. The ball is well-made and is one of her favorite toys. if I tell her to go get her ball she will even go under the bed and is able to grab it and carry it up the stairs to the bed for playtime. It also makes it easy when we are in the yard when I throw it. It is light enough for her to carry and bring back to me. But, as I said , I did have to adapt it so she could get a grip.

Easy to grab and throw!

Size: Medium

Our puppy loves this ball, although it gets stuck on her teeth sometimes, but she gets it off just fine! Easy to play and throw. She has a blast catching it, too!

Keeps my dog happy

Size: Medium

This is a fun toy for our cavalier. It's pretty versatile in how you can use it, which I like because it allows me to change things up to keep my dog engaged. He's also an aggressive chewer and he hasn't destroyed it.
