Bright color and tough skin both great
Color: Regular-Orange, Size: 2.5"(Medium)-12 Pack
These tennis-style balls are, as promised, much tougher and thicker-skinned than an ordinary tennis ball, being made as a fetching ball for dogs. I bought them as foot covers for the legs of walkers used by the elderly, a very popular use. They work extremely well to protect rugs and flooring, and to make a quiet gliding cover, easier for seniors to move smoothly without snags. The usual tennis balls used for this purpose wear out pretty quickly, but this ball was made to be repeatedly fetched and gnawed on by your Rottweiler, so it's a big improvement. You will need a good cutting tool to score in the crosswise slits where you insert the walker leg; it's too tough for your household scissors, but that's just the point, right? It's tough.
Very much recommended!

Not great quality
Color: Regular-Red, Size: 2.5"(Medium)-12 Pack
My dog is 7 months old, about 35lbs as of this review. These balls barely lasted a month as they all kept breaking if thrown against anything or just bounced repetitively. The color is good so that you can see it better in the dark, but I would not say these balls are worth the price.
Update 2023-12: After posting my review the seller contacted me and provided me with two free sets of balls as an apology for the bad quality of the original set. So far these are holding much better with my dog and she loves to play fetch with them.
