Good luck with the NV raw. It is convenient and easy. If Chloe would just EAT, I'd be still giving it to her. She likes to hem haw all day before gettng around to it. You just can't leave raw out like that. If your dog is the type to just eat it and be done with it, you're good to go. it is supposed to be really good food, and that Lamb one is the one Chloe liked. She did not like the chicken and turkey one at all. Also, go to the website (google it) and fill out the questionaire. They'll give you a coupon for a b1g1 free of those medallions.
As far as feeding them both, I have heard mixed reviews. I have heard that it is not good to feed both kibble and raw at the same time because the kibble takes a long time to digest and the raw presents new bacteria.
I have also heard others say that is bogus and that there is no trouble giving both.
Just go easy and see what works best for you.
