Cookie just loves greenies. She hides it first for a while and then she goes to town chewing on it. Occasionally she'll eat a whole small or medium size one in a few hours. She is ok afterwards but it comes out the other end GREEN
But other than that, I've been giving them to her since she's been about 6 months. She also LOVES the flavored bones (edible). I think they're cornstarch. The have flavors...peanut butter, cheeseburger, and fiesta chicken. Peanut Butter is her favorite
. I never give her pig ears or raw hides because they were not recommended for Yorkies.
