because I don't feed my dog meat from the supermarket - a chicken back, or such, it's not the same as "raw". It comes in a bag, I pay for it (which, by the pound, isn't THAT much more expensive than quality meat in a city supermarket...) and has non-meat ingredients.
I give her the primal patties. I bought a small tube of grinds to supplement because sometimes her tummy grumbles at 3am...but it was very messy and it doesn't last long enough, thawed, for the reasons we tried it.
It's been awesome for Lucy - she eats it so fast, licks the bowl clean and jumps for it when it's meal time.
I also give her marrow bones for her teeth and general jaw health. I don't buy primal bones. Primal sent us a box of goodies and they included their brand of treats which she LOVED (but they're VERY $$$).
