Gonzo LOVES Greenies! I think he would be in ecstacy if his diet consisted completely of Greenies, it's like giving candy to a kid. =P At one point, he got a Greenie every other day or so, with not a single side affect except for clean, shiney teeth! He still gets about 1 a week, but they are ridunculously expensive so I limit him. Ribs and marrow bones clean his teeth well, but Greenies work just as well.

As for rawhide, I mostly do not feed it because Gonzo doesn't like plain ol rawhide. I never feed anything rawhide-like from out of the USA. He does get a variety of the Merrick chewies, because we sell every single variety at the feed store I work at! He likes bully stix, lamb ears, and dried sausage chews the best. He also loves Texas Toothpicks, which are cow tails so they're basically rawhide.
