Small balls for all of my dogs
I have 5 dogs of various sizes, and I have found that they all love the smallest tennis balls. The biggest won't touch a 3" tennis ball. I also have 2" balls, but everyone's favorite is the 1.5" ball. Now I have 40 of them to last a while!. This package comes with more colors than I've ever had, and they're all very visible. The purple is the least visible, but you can still see it in the grass. We have a large field and constantly throw the balls out. The dogs get plenty of exercise running and jumping after them. The dogs love the squeakers. The big dog (only 35 lb) can put the whole ball in her mouth, but she is not the type to try to swallow it, so I'm not worried. (I know there are some dogs out there who would swallow anything.) She just wants to bite down on it and hear it squeak. It's so much fun watching my dogs and their squeaky balls. The set came with a mesh bag for storage, too.

Works but fibers are an issue
Size: 10 Pacck, Color: Multicolor
These were great for my small Yorkie puppy. She had to is bite issue and we needed these tennis balls to help her stretch and correct her jaw. Squeaker works well. The chewing helped but it wasn’t necessarily “chew resistant”. the little fibers from the ball will start to come off and dog will hack a bit. For that reason, I am unsure of the safety of it long term. Must be supervised always. Will try a def brand next time but this helped our lady w her jaw pain/issue.
