I love both Blue and TOTW. One of my dogs is allergic to specific foods and she has done well on both. Blue does have many different varieties. I've used Wilderness and Basics without a problem. And a few others on here also think the quality of the 2 Brands you mentioned are good.
If you slowly ween your boy off whatever he's currently on and give one of the new brands a go, you can test & see how your dog does on it. Pay attention to his stools/gas and coat/skin and over all health & energy at about a months time. If all seems good, then keep on it. Many times it's the bad fillers and specific food ingredients that do our dogs harm when it comes to commercial foods. As for recalls, Blue did have some a time back but you see it can happen to any & all foods. Even fruits & vegs we, the humans, consume.

I feel they took care of the problem and hopefully (if anything) learned to have better quality control out of it all. But who's to say a $1000 brand doesn't one day slip up too?

I also took a long time sifting through the net and articles trying to research commercial brands and still feel confident with Blue & TOTW. I spent a lot of money, time & worry helping my dog get better and I quickly realized you really have to figure out what is best for your own dog in the long run no matter what other people say. It's your baby and each situation is different.
