Here is the site. They are still getting stuck. Greenies have killed plenty of dogs and cost owners lots of money in emergency surgery. I used to give Ellie Greenies occasionally and she still got peridontal disease (pretty severe) so they didn't do any good for us. I don't give her any chews now since she is older. She doesn't need them. I brush her teeth though. The only thing I would consider are bully sticks and the thought grosses me out and they are way too high in protein for Ellie's liver.
