OK, so my fiance and I just brought home our 8 wk old pit bull/American bulldog mix. I've had a pit puppy before which I raised for almost a yr. We rehomed her when I divorced my ex a few years ago. So my question is; where can I find samples of free dog food to try for my lil guy? I want him to have less byproduct and more natural foods. I want him to have the best life quality. Any suggestions on food, coupon sites, deals, promos on foods, also any vets in comparison to safe harbor?
