Not as tough as Wilson’s. Easy to be chewed and busted by pet.

Squeaky fun!!
Color: Multi-colored, Size: Small - 12 Pack
These are perfect they fit in my hyper pet shooter and they squeak too! My dogs absolutely love themZ. Seems to be good value and I think they will soften up over time.

Small and squeaky!
Pretty perfect! Great size for small dog and they do squeak. It’s helpful to use both hands when getting the ball to squeak. It’s a bit difficult with just one hand, but that can’t be avoided because the size of the tennis ball is small. We use these inside and outside to exercise our puppy.

Milo approved!!!
Color: Multi-colored, Size: Large - 4 Pack
My dog, Milo, loves these squeeky balls. He is a larger dog but not huge. He's about 60 lbs. They are the perfect fit to his mouth. Soft enough for him to chew on but sturdy enough to hold up.
