Deceptive Advertising
There's a little bit of false advertising going on here unless you thoroughly read the description. There are three balls in the picture, but you are only purchasing two. Always read the whole description before buying!

Not the same rubber.
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!
