What do you prefer? I need to pull the pit bulls off this great life kibble, it's too fatty for them but I'm not sure what to put them on. For starters at my new job I can get ToTW, Acana, Canidae, solid gold, and Evangers at cost. I was going to do Fromm senior but I figured I'd ask about these first. I need something without such high calories, they're gaining weight on way too little food and my guilty conscience hates feeding less than 1 cup per meal. None of the formulas at work are seniors, except the canidae senior & overweight, but I could probably ask for that to be ordered. Suggestions? I need grain free (which these are).
