You know I asked my vet about the normal greenies and they told me that the only reason that they hurt those dogs was because they were not feeding the right amount...Or they were giving the little ones to big of greenies and the big dogs the little greenies and they were choking on them...I have been giving them to Tiny since he was little and nothing bad has happened....He loves them...He only gets 1 every 2 weeks....I haven't had any problem with them?
