FOUND IT!!!
My dog had found one of these on the road and absolutely love this toy it had hole in it from other dog's teeth hardly bounced but he loved it. I looked in every store I went to trying to find this toy could never find it finally was looking for dog toys found this package, was hoping it was the same thing. Oh it was! When I say my dog loves his toy that is an understatement he has played and will play with this for hours no problem leaving him at home alone he is entertained. If he's not throwing this around and chasing it he's laying down and sleeping because he's wore out. It's squeaky it's bouncy and hopefully durable it is soft fits in his mouth and he just has literally a ball with it. He is laying here panting so much right now from playing with this ball this morning to your dog a favor and yourself get these balls get this toy. On the other side of that you might have to take it away from them when you go to bed at night because ours wants to play with it at the weirdest times and it is squeaky thanks so much hope this helps

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.
