Durable
Color: Hammer, Size: 7 Inch
Even my monster hasn't been able to chew through these in a few months, and he has destroyed one of the black Kongs in the same time frame.

Tough to destroy for aggressive chewers
Color: Wrench, Size: 8 Inch
My doggie chewed out stairscase, the sofa, my shoes, and would destroy anything labeled pet “tough” toys. This stopped her from destroying!! Soo cool and cleans her teeth too. I got this one as gift for other retriever fams! Super cool. Doesn’t smell bad and its lightweight but durable like crazy.
