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.

Great Toy for Chewers!

Color: Hammer, Size: 7 Inch

This is one of my dog’s favorite toys! He will chew on it for hours. It is durable and takes him a while to make it indistinguishable as a hammer. No smell to it. The rubber bits do come off so I have to check it and make sure he doesn’t eat them.

Good toy

Solid value for the $. The hammer seems particularly good, my bigger dogs like to hold it down by the head. I bought a 2nd.

My heavy chewer loves these! I had to get the whole set because come on! Skye steals ALL my husbands tools so when I saw these and saw they’re real wood! (My dog is a wood chewing machine) (ask my deck) anyway these work and keep his teeth off my furniture! 10/10 recommend!
