Squeaks for a while
Size: Medium, Style: Squeaker
I've got probably 10 of these, now. The squeaker fails pretty quickly. But our dog still likes them, just not as much as when they squeak. I'm tossing these a good 75 yards and farther. The Chuckit glowballs make sounds through their holes so no separate squeakers there. Dog really likes those glowballs.

Great quality but the squeaker doesn't last long - still a good value
Size: Medium, Style: Squeaker
I have golden retrievers who never get tired of playing balls. These are VERY durable. No seams to split. They tend to chew as they bring the balls back, so the squeaker doesn't last long. Would highly recommend these. I have them on auto-delivery!

Highly recommend
Size: Medium, Style: Squeaker
My dog loves these! They are now his absolute favorite! The squeaker lasts a lot longer than most. The rubber isn’t hard on his teeth and he likes how squishy they are and continues to play with it long after the squeaker dies. Highly recommend and will be buying more

Great fetch toy.
Size: Medium, Style: Squeaker
My dog loves these balls. They are a bit softer than the normal ones and bounce well. The squeaker is not too loud but definitely makes the ball more interesting. I highly recommend these.
