I've highlighted the bad ingredients. If you go to
www.dogfoodproject.com , you will find an explanation of why these ingredients aren't good.
There are many, many high quality dog foods out there. Some of them are:
Canidae
Timberwolf Organics
Orijen
Innova
Nature's Variety
And there are many more. With a high quality food, you actually feed less of it to your dog (so the prices are very comparable with low quality foods).
