Even though home made dog food is the best. some people can not and do not have time to do so. All I can tell you is that I have done hours of dog food research. I do make food for my dog some times. I do not feed any thing I could get from target, walmart, petco, petsmart, ect……
My favorit website that has helped me sooooooo much is http://www.dogfoodproject.com. I love this site. she keeps it up to date.

Good luck with your dog food quest. and don’t give up.

I have changed to butchers dog food after a recommendation from a friend, my dog suffered from dry skin and also very soft stools, since changing to butchers she now has a gleaming coat, hard stools and enjoys every mouthful, cannot recommend it enough, she is a staffie cross and people remark what a lovely shiny coat she has even the vet, so do give it a try, butchers only use good ingredients and always try their products on their or friends animals before putting it on the market, best food ever.
