I’m impressed with how durable these balls are! The rubber is nice and thick and tough, so my dogs have been unable to rip them apart yet. The spikes help clean their teeth when they chew, which is a plus. After weeks of use, the rubber is not sticky and does not smell. They haven’t lost shape or bounce. The size is perfect for my large shepherd husky dogs, as well as my medium sized Heeler. The loud squeaker in 2 of them has stopped working, which I’m not sad about. As a matter of fact, I’d give 10 stars if all of the squeakers stopped squeaking, lol! The package of 6 balls was a great value!! Will definitely buy again.

So much fun

Size: Large Set of 3

The dog and my wife love these. The spines keep your the drool you have to touch to the minimum. Very durable for a dog that loves his toys and destroys them. Squeak is fun but got a little much. Just stabbed knife into the squeezer hole and silenced them right up - still kinda squeaks, just without all that high pitch goodness.

Great for playful dogs

Size: Medium Set of 6

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!
