Squeaky balls for big dogs
Color: Squeaky-4 Pack, Size: Medium
I wanted a cheaper alternative to the Kong squeaky balls but unless you have big dogs that have powerful jaws, it is challenging for small and some medium dogs to squeak these. My dogs lost interest when they realized they couldn't squeak them. I will have to pass them off to a friend who has large dogs.

Moms dog here…reviewing cos it’s mine!
Color: Squeaky-4 Pack, Size: Medium
Moms corgo here. Reviewing the squeaky balls mom bought.
First off..they’re green. I don’t know what green exactly is cos I’m colorblind, so whatever that is it is and because it’s mine, I like it.
Secondly, they’re fluffy. It’s an annoying texture that I like to peel off, but these are tough and peeling them is a struggle.
Thirdly, the bounce. I don’t know where these balls think they’re going to think my mom is so repulsive, but they bounce just high enough to catch them and bring the escapee back to mom when I feel like they need to go back to her, otherwise, I take them to a safe spot to release into the wild…but mom always captures them and they always escape. I tell you, it’s a vicious cycle.
Fifthly…the squeak!! That rotten vulgar noise!! I want to unalive those things so bad!! Balls in the past were no match for my jaws of death, but these?? These are resilient and have quite the will to live! I have yet to destroy one!!
To wrap this up…Corgo approves and declares them mine. I like them. I think your doggo will like them too. But you can’t have mine..cos they’re mine.
*drops the corgo mic*

Not for aggressive chewers
Color: Non Squeaky-12 Pack, Size: Medium
You get a good amount of balls for the price. My dogs loved them but unfortunately they did not last long. That is not the company’s fault, my dogs are very toy aggressive and destroy almost every toy.
