I just received these today. I already have two of the same size direct from the local pet store. The one thing I liked about them that made me want to buy more - my 13lb dog could chew on them all night and never leave a mark. The red one I received was as expected. The blue one I received was not made out of the same rubber. It was softer. We played catch a few times and it didn’t bounce the same. I looked away for 5 minutes and she had it already starting to shred. Not sure what happened but 1 of the 2 balls I was sent was not up to par, possibly defective.

Best Balls Ever!!!

Size: Medium

These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!
