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.

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