If I could give this six out of five stars I would. I’m so grateful that there are multiple size options so I could pick the perfect size for my puppy. As a 4 1/2 pound puppy, I got him the smallest size ball. It’s the perfect size for him and he’s able to pick it up at any corner with the strap zone on to it. It’s very thick and durable but also lightweight so my 4 1/2 pound puppy is able to run with it in its mouth easily. He loves chewing the tabs and they haven’t budged or broken. It’s excellent quality and worth every dollar. We used this ball indoors and outdoors all day long, it’s his favorite toy!!
