The food decisions are exhausting. We feed BB Wilderness Salmon. I tried several high quality foods before settling on BB as it was the first that Samantha's digestive system could handle. Both her and Mulligan love it and we haven't had any issues. Before we fed the Salmon Wilderness we fed a different BB Salmon blend and Large Breed Chicken and Rice (I think) before that.
I would agree that the BB reps are obnoxious. One hassled me the other day even though I had a bag of their food in my arms. I was looking at organic something or other dog treats (that weren't BB... gasp!).
Good luck and I hope you find something that will work for your dogs!
