DH and I just rescued a pretty bad ass dog. He is some sort of schnauzer/cattledog mutt, and he is awesome. The rescue group wasn't really clear on what they were feeding him in the three weeks they had him, before that who knows what he was being fed at the kill shelter he was at in Miami! When we got him we started feeding him Science Diet for sensitive stomachs (he was having some GI issues, and I know it isn't wise to just switch food cold turkey on dogs, but we had no choice)
In any event, he is doing great now. We have had him for a few weeks and all his GI issues seem to be resolved. I am now looking for recommendations as to what you feed your dogs. We are open to any suggestions. He seems to like the Science Diet brand, but sensitive stomach doesn't seem to be needed anymore.
