When it comes to chewing, is your dog a beaver, a Ferengi, or an all-day sucker?
I just handed identical chewies to Luna and Ruby, and went and got a geriatric safe chewie for Cole. When I returned, Luna had beavered her chewie and all that remained were a few crumbs to clean up. Ruby is still carefully gnawing from one end to the other, shifting from one set of molars to the other to get an even work out. Cole is usually my Ferengi because he likes his chewies pre-softened and pre-moistened. Back when he had strong enough teeth to chew with the rest of them, I'd hand out three identical ones and he'd just wait until one of the girls had one started just right. Then he would trade with her. At first there would be confusion. "Hey, he took my chewie!" then "Hey, look, here's a brand new chewie!" and finally, "Who would trade a brand new chewie for a used one? Who cares: mmmmm...chewie."
So what kind of chewer is your dog? How do you choose chewies appropriate for his or her style of chewing? Are there any chewies you forbid your dog to have (and why)? How do you supervise chewing?
