I have to say that Premium Dog Food is WAY better than the average Dog Food from the food stores and big chain pet stores. Please look at the ingredients. I would NEVER feed my dogs anything that includes BY-PRODUCTS in any shape or form. By-Products are pure crap, they include parts of ANY animals (road kill animals, dogs/cats killed in shelters, unfit parts from slaughter houses, cancerous and diseased organs, feet)
By-Products = Parts of Animals that are NOT fit for Human Consumption
Everyone is entitled to their own opinions and are free to purchase and feed what ever they want. BUT honestly, better food that you can get at a Smaller Pet Shop only costs maybe $2 to $4 more a bag.
To me - My Babies are Worth it
If anyone is going to switch food, please do it slowly and gradualy as to not upset the GI track.
