I thought I would share with you an interesting article on the mass produced dog foods, I found on Dogs Naturally website today, it's such an interesting read:

Did you know that "40% of dogs are obese. 46% of dogs and 39% of cats now die of cancer. Heart, kidney and liver disease are epidemic. Like people, dogs are what they eat. Save your dog a lot of suffering, and save yourself a fortune in vet bills, by learning the truth about your dog’s diet."
