Not for chewers
Size: Medium Set of 6
Not for chewers, but I bet non chewers would like the. Good quality, bounce, fun color and texture. Fun while it lasted, but didn't last long with my 2 year old pitbull. We've been trying to find the replacement to his durable spiky ball that went down a sewage drain. Right now the Chuck-Its are the ones that last (minus just one)

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.
