I just tried those greenies for my 2 gurls, and they loved them. It kept them busy for about 1/2 hour, and they ate the whole thing! I gave them one a day now, for a few days. Is that okay? Or is it too much? Or can I give them more than that, since they love them? Money is not an object when it comes to my gurls. LOL! Thanks for all of the greenie help, guys.
