MY CHIHUAHUA LOVES THESE BALLS!!
Color: Samll Set of 8
My little chihuahua, BamBam, is addicted to balls, especially little balls that squeak! However, any balls that have material on them, BamBam will tear them apart, swallow the material and then get an upset tummy! These balls saved the day! BamBam LOVES them & she cannot tear them apart! They hold up so well! No matter how much BamBam plays with them, they keep squeaking away!

Squeaky ball
Color: Large Set of 4
Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.

Really indestructible
Color: Yellow
As advertised. I have an obsessed 16lb mixed breed dog that has destroyed everything purchased that says indestructible. Until now... These balls really are indestructible. She loves them and plays with 2-3 at a time. Chews on them and still going. They are the size of regular tennis balls. Others are slightly smaller. These are great and bright... Mooky highly recommends.
