All squeaker ball companies need to start doing this!!!!
Color: Orange - Pink, Size: 2.5"(Medium)-4 Pack
So first thing I want to say is that the manufacturer of these balls has thought of something that I am honestly shocked nobody has yet thought to do. They put the squeaker reed UNDER the fuzzy shell. GENIUS! I mean really, why aren't all squeaker ball companies doing this?!?! No wondering when it will finally pop out (or in) and it definitely prolongs the life of the squeaker significantly. My staffordshire/pit bull mix adores her squeakers, that said, they never last long especially when they are in a ball (her absolute fav toy on earth) The squeaker being protected alone warrants a 5 star review because it is simply genius.
The fuzzy shell has yet to deteriorate and we have had these balls now almost 3 months so they have already outlasted other brands too. Now as for the sound itself, it is definitely different from a typical squeaker, not necessarily a bad thing. It is a "mild" squeak, not obnoxious a bit high pitched. Sounds more like a baby toy squeaker than a dog toy squeaker though....I'm not quite sure how I feel about the squeak. My dog has a preference for squeaker sounds. She prefers the little squeaker sound over the deeper louder sound from the bigger squeakers, these are closer to the sound she prefers but she doesn't LOVE it like I had hoped.
The only other thing is that the ball itself feels as though it was blown up and plugged tight. Meaning (and believe me when I tell you my dog has a strong jaw) it is harder than most to make these balls squeak because you can't squeeze all the way down on the ball. It takes me two hands to make them squeak so my dog has a tough time squeaking them. She continually tries though so they are keeping her occupied. Overall I do recommend these balls because they are far safer than most eliminating the concern for your dog accidentally eating the squeaker and the longevity of their potential life. Try em, they are rugged enough for heavy chewers alike!

Tough enough to take rough play.
Color: Multicolor A, Size: 2.0"(Small)-6 Pack
They are smaller than I thought. That’s on me because I didn’t see the size. My dog loves them anyway and they are sturdy

Lucy The Dog Approved!
It's really not for me to say, with exception of the orange-blue color, which is ideal for still life. But the best part is how unglued the Lucy Dog gets at the sound of the squeaky toy knowing the hall leading to my apartment is instantly converted into a Dog Run. And she gets equally excited at the sight of any grassy area when on bike rides. So a feature that is truly the dog's bollocks is it's the perfect size for both Lucy's petite mouth and the all important emergency spare that fits securely under my bike saddle. In short, sublime perfection in Lucy The Dog's expert opinion.

If you have dogs that like to play fetch, these are a must have!
Color: Orange - Pink, Size: 2.0"(Small)-4 Pack
My pups love these sp much, they won't play with any balls other than these. Not sure if it's the small size, or the fact that they squeek, but they def were a hit.
