:?: I bought some greenies for Buffy and Chico, they love them. The only problem is every time Buffy eats one she vomits and has runny stools about an hour or so after she eats it. I can also tell she doesn't feel well, she goes in her crate and hides. Chico does not have a problem with them. Chico is 3 months old and Buffy is 2 1/2 years old. Has anyone else had this problem?[/b]
