These are great! I unfortunately had to return them because my dog is 45 pounds and they’re too big for her. She couldn’t carry them constantly in her mouth. But the quality, colors, squeak, and bouncy effects are perfect for playful dogs or simply getting your dog to play more. I’m going to see if they have smaller sizes available. Great value too!

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.
