Mine use the NV raw, too. They don't like the lamb but love the chicken and beef. I bought a couple of the bones once cause I had a coupon, but they didn't seem real thrilled with them and I think the bones are too big. Plus they made a mess on the carpet.
We feed twice a day - once around 8-9 A.M. and then around 5 P.M. My dogs range from 6 months to two years. They get bully sticks and an occasional treat. I give them Yorkie Yummies at the grooming table so they will learn to like being there more.
One of my two year olds has been eating NV raw since she was a puppy. (I got her at six months) She doesn't have health problems and is at the perfect weight for her size. I really like NV and will keep feeding it.
