Why is natural dog food better?
The difference is in the ingredients. Commercial dog foods are made with "Restaurant grease and garbage; meats and baked goods long past the expiration dates from supermarkets (Styrofoam trays and shrink-wrap included); the entrails from dead stock removal operations, and the condemned and contaminated material from slaughterhouses" – Food Pets Die For.
What this means is that the commerical companies like Science Diet use ingredients that have been deemed unfit for human consumption. Top add to that, they make up the bulk of the food with corn and other grains that dogs are not able to digest and then coat these undigestable grains with the grease, garbage, expired meat, entrails and contaminated materials to make the food have a more appealing taste to dogs.
Good, natural dog foods like Orijen, EVO, Taste of the Wild, etc. use real meat, real vegetables and real fruits that your dog would eat in the wild. Have you ever noticed how the commercial brands portray their dog foods as if there’s real steak or chicken in them that could be consumed by a human-being? In reality, if you saw the meats they put in their food, you wouldn’t let your worst enemy eat it. The premium dog foods do use meats, vegetables and fruits that are healthy enough for human consumption (even though I don’t recommend eating dog food). The very stuff you put on your table for dinner is used to make the food your dog will eat. The don’t use contaminated meats from sick animals or meats that have long past their expiration date.
