Quiet squeaker!
My puppy loves them and I love that the squeaker isn't obnoxiously loud like her other toys.

sufficient for my dog..
Not very durable.. Dog has chewed one in half pretty quickly and found some smaller bits around the house. This could pose a safety risk to dogs that try to also swallow these bits. If your dog is like mine and would rather play with them instead, they are cheap enough to replace them.

Stands up to my aggressive chewer.
The squeaker stopped working almost immediately, but my dog didn't care too much. He still keeps chewing on these balls, and so far, they have stood up to his tough jaws.

Dogs love the bounce and squeak
My dog loves these and he isn’t a fetching breed. He loves chewing on them while they squeak. He’s a Great Pyrenees and the chewing is good for keeping him occupied when I’m not home. The neighbor dog, sneaks through the communicating gate and will steal one for herself. She’s a cattle dog/ husky cross. The other neighbor has a lab and he absolutely LOVES how these ball love to fly through the air and bounce so well when they hit the ground. Get them
