These Ones Last - Great for Small-Medium Dogs
I really want to give 5 stars but after a week, 3 of 5 squeak no more. Regardless, more of a donut shape and great for small-medium jaws. Safe to throw around the house and the soft latex easily handles bite after bite without falling apart like other tennis-ball like dog toys. These ones last and are good for hours of fun.

They KNOW that latex smell and they are hard when you first get them!
My dogs love these! I just noticed I bought them 18 TIMES! 😧 I know it's the laytex smell and they try so hard to get that squeaker out! I'd yell "new toys" and throw 3 in different directions! I know they are expensive but my dogs and I have SO much fun 😊🐾🐾

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.
