I love a man with a simple and straightforward character!
Just make sure you test him with the size of rock you intend to use, first...in case he turns out to be a rock chewer. We brought in 1-inch, 2-inch, 4-inch and 6-inch samples and put them on a coffee table. The two smallest disappeared almost immediately in the mouths of dogs....the 4-inch one got carried off a few minutes later. So we settled for 6-inch rock as the one least able to be eaten.
