HI, I really need some advice on what to do about my Minnie, She's a 7 month old morkie, she has been on Royal Canin since I got her in November and now she won't eat it, I don't know what to do and her poops are not good. I tried mixing yogurt as vet suggested and told me no more chicken because that's why she stopped eating it but i was giving her the chicken so she would eat the nutra cal. I'm just so worried about her. any advise would be greatly appreciated. i like my vet but he just wants her to eat the royal but she doesn't like it anymore

thanks for any suggestions
Sherry and Minnie
