3.5, Not 3.0
Color: Medium Set of 6
These balls were almost exactly what I needed. I was replacing my boy’s favorite ball, which is the 3” squeaky, spikey ball that fits in the chuck it launcher. Unfortunately I saw the shiny object next to it and because there were SIX balls and a dollar less, I failed to see that these are 3.5” balls instead of 3”…. Great balls but no fitty in the slingy. Buyer beware. No chuck it no problem. Save a buck.

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.
