I was just curious....I have heard that greenies can be dangerous for smaller dogs....and since my Daizy loves them just curious if anyone else feeds greenies to their little furballs?? I also heard that one Yorkie almost died because he got really sick from eating too many greenies...wonder how many is too much?? Daizy loves having at least 3 a day...she's 5 lbs...so any thoughts??
