You guys.....please do a search and read about all of the bad things about greenies. They stay in the intestines, they don't break down completely in the stomach, and it can get lodged in there and eventually cause death! Please look it up. Vets even told us this on Terrific Pets.com. They are also addicting....that's why they love them so much. I stopped giving them to my girls when I found out. They were so disappointed, as I always gave them one before bed. They couldn't understand why, of course, and I felt like a big meanie. But no way could I give it to them anymore. I had just bought a new bag too.
