Okay, i'm seriously getting frustrated by all the food problems I'm having. I literally live out in the middle of nowhere so I'm really limited to what I can buy. I started my 14 wk. sheltie out on Nutro but recently found a store that carries Royal Canin. I bought him a small bag of the med. puppy formula and he LOVES it. I thought I was doing good by switching him to Royal Canin, but now I'm finding posts on here that say it isn't a good brand. Is it or isn't it?? I can't get anything shipped to my house...just not an option. What are your thoughts on Royal Canin as compared to Nutro brands.
