I'm not terribly thrilled with Champion anymore like I used to be. After reading some things, it took a long time for me to actually believe them, but I've read too many iffy reports about them lately. They were also sort of bought out recently (not like P&G boughtout) but failed to mention it, but their under new ownership and a new CEO who had no experience in dog food. The company was sold to Bedford Capital in 2011. Frank Burdzy was put in by the new owner as the CEO. Prior to that he sold propane gas and fertilzer. There was never an announcement by the company. But they have a lot of claims about their food that I find to be bogus and their very tricky with a lot of wording and ingredients. I don't know, I'm still not sure how I feel about them totally, because I used to LOVE them, my dog always did well on their foods for the most part, but I don't feed it anymore because of the price increase/bag decrease and new ingredients. Wasn't happy with all the peas, beans, lentils, etc. I question how much meat is actually in there. I also have yet to hear of who exactly formulates their food and what credentials they have etc. But I almost considered trying their Singles line again because Jackson keeps getting bad eye boogers on Fromm and he always had a clear face on Acana Singles, but I'm not sure.
I've become a lot more concerned about a lot of these 'holistic' companies than ever before. I still wouldn't feed Purina or anything, but I also don't think the majority of all these '6 star' rated foods are all their chopped up to be. But I've really done a 180 on my thought process on dog food.
I definitely don't trust Blue Buffalo either. A bunch of dogs died on their food because of a vitamin d overdose. It's also the food that I've heard MOST come up when dogs have GI issues. Not to mention they're made in like 5 different manufacturing plants. Just not sure I trust they have employees at EVERY factory over-seeing EVERY little thing they do.
Bottom line is, I don't trust many of them, but what can you do? I think you just have to go with your gut, and what your dog does best on, and what you feel comfortable with. I wouldn't feed anything by Diamond, but lots of dogs do great on it, and honestly the chance of my dog becoming ill on a food by Diamond is probably one in a million, but it's just still not something I feel comfortable with.
