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.

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!!
Seem to work fine in the ChuckIt.
As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣
