I'd stay away from greenies and anything with rawhide or by products in it. I just feel those things are entirely too dangerous to give to someones pet. Bully sticks are great, but you have to be careful where you buy them from. Some places, the way they manufacture them and where they get them from, they can be as bad as anything else for your pet. Make sure they are from free range fed buffalo. I get mine from
www.beyondspoiled.com and they are called Pixie Sticks! I also get them at Pet Supplies Plus and they are by Merricks. Hope this helps you!
