Good toy
Color: Hammer, Size: 7 Inch
Solid value for the $. The hammer seems particularly good, my bigger dogs like to hold it down by the head. I bought a 2nd.

Skye loves it!
Color: Hammer, Size: 7 Inch
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!

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.
