Almost Indestructible!
Size: Medium Set of 6
My dog LOVES these balls, and it's all about the squeaker (which my husband hates). The size is great and I don't worry about it getting lodged in her throat. They are very durable too. We had one lone ball for YEARS and I forgot it ever squeaked, but it was still in tact. I searched for a replacement because I was so impressed with it. Very happy to have found it. I just ordered some for my son's dog too. The squeaker may eventually come loose, but it's worth the money to buy again!

The most durable and fun dog toy of all
Size: Medium Set of 6
Most durable and fun toy of all. The only thing that I have found that can destroy these balls is a lawnmower. Probably good for keeping teeth clean too.

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.

Great for aggressive chewers - Great for clean teeth
I never thought these would stand up to my 60lb pittie puppy's chewing. But they are far and away her favorite toy and are holding up beautifully. One squeaker insert bit the dust -- which is not bad since it gives us one silent one. But otherwise they are holding up superbly to her powerful jaws. We have tried a lot of toys. So far, all the "for aggressive chewers" toys have been torn apart within days if we are lucky -- usually it's minutes. But these balls show little-to-no sign of wear. The squeakers are very loud which she loves can get a bit tiresome. So, as I mentioned, having one silent one is a great option. And she really likes the texture. She loves them so much, we bought a second set and will probably buy a third to have in reserve. (We are realistic and don't expect them to last forever.) All I have to say is "where's spiky ball" and she instantly stops what she is doing and goes on the hunt. A great buy!! (NOTE: It's been almost three months and one is just beginning to show some damage. Given that she plays with them non-stop, they've showed amazing durability. And everyone comments on how clean and beautiful her teeth are. I don't brush them or give her dental treats. So it has to be these balls!!)
