Best Tennis Balls Ever
Color: Non-Squeaky - Pack of 12, Size: Medium
Admittedly, I haven't had these for very long, received on Jan 7 and today is Jan 19., 2021, only 12 days. But, we have a terrier mix who hasn't found a tennis ball she couldn't destroy given an hour or two. That is until now. Twelve Days later? She hasn't managed to destroy it at all. We have a puzzle cub that came with a ball inside it. It only took her a couple hours for the ball to rupture at the seam and another 10 minutes to completely destroy it beyond recognition. We put one of these balls in there and here we are over a week later. Not only has she not destroyed the ball but she hasn't been able to get this one out. She looks so silly trying to carry the ball inside the cube. It's hilarious. Anyway, I digress. I would totally recommend this toy for an yone who has a dog that lives to play fetch bit keeps destroying the balls. By the way,
Update: Jan 31, 2021 and still going strong. No signs of damage.

Perfect tennis ball size.
Color: Non-Squeaky - Pack of 12, Size: Medium
Like most doggy balls they dont last as long as real tennis ball, but a real tennis ball can wear down her teeth. Great colors, tho in a few days they are yard colored cuz of the slobber and nature on it. Love the handy mesh bag for keeping put away until we need to get out a new one. My dog loves the no squeaky. To her squeaky is inside toy and too distracting for outdoor play. She really enjoys fetching this ball.

My Dog Dreams Of Squeaky Balls 🐶
Color: Squeaky - Pack of 12, Size: Medium
My dog really loved these balls when I got them. It's a great variety of colors, the fabric is well-attached, and I LOVE that the squeaker is hidden under the fabric, reducing risk that it falls out and gets eaten by one of the dogs. The net carrying bag is a nice touch as well.
Unfortunately, these balls do not hold up to much play. I have a medium-sized dog and he likes to mouth the ball when he catches it to squeak it. The squeaker broke on every single one of these within the first play session. Thankfully it stays contained in the sealed ball, but still, it would be nice if it lasted a *little* bit longer.
Beyond the squeaker issue, my dog wears these out within a day or two of play. Keep in mind that he LOVES playing fetch and we will spend a good hour playing per night. Usually the fabric starts to detach and the ball will start breaking at the seam (the ball is two halves glued or sealed together).
That may be the fault of the dog, though, since he does squeak these an awful lot while we play. Buying a stronger ball may not be an option because he enjoys the ones that are easier to squeak like these are!
Overall I'm fairly happy, I just wish they lasted a little longer or cost a little less. 🐶
