Review on Penn Ultra-Blue Racquetballs (2 cans) – Premium Quality, Extra Bounce, 3 Ball can by Sri Mims

This is for a German Shepherd Toy Review. If you use them for a paper shredder, read on. We thought we finally found a ball that can't be destroyed. Our GSD Layla destroyed all the balls, even the hard ones, when she hit one of those racquet balls my son has. This went on for quite a while so we decided to order more. Then when she started using her molars to try and rip them apart, we found they broke into tiny pieces that could be eaten, which is obviously not a good thing. Unsuccessful, but the search continues. PS I'm giving 5 stars because it's not because of the bullets which aren't fit for their purpose.
