I found this website that talks about how commercial pet food is nutritionally inadequate and many deficiency diseases dogs have developed are the direct result of poor feeding. There is also information on how dogs are over-vaccinated and its horrible side effects.
This is very informative information that I appreciated reading about and I think you will too! You should visit, Canine Health Concern @ http://www.canine-health-concern.org.uk/
Thanks and Happy Reading!
