Disregarding the horrible pet food ingredients you will see listed below, poor quality feeds are mostly grain based. These grains, when consumed by a carnivore will be metabolised by its body into sugars.
Dogs don't process sugar very well. This excess sugar can lead to build up of ammonia on the brain which ironically can lead to behavioral issues such as a hard to train, or out of control dog.
Further, sugars can feed certian cancers and lead to a variety of other health problems such as canine diabetes, kidney and other organ diseases.
Just keep this in mind if you're considering a grocery store brand, poor quality feed for your pet.
Commercial Pet Food Ingredients
The commercial pet food industry is absolutely booming with little regulation to assure quality! Commercial pet food sales are over 20 billion dollars a year.
A perfect outlet for the slaughterhouses, this provides a market for their waste! Scraps, organs, diseased and cancer ridden animal parts, (could be any animal), things not fit for human consumption. Don't forget the mills, after all, they provide the spoiled grains, wheat and left over fillers that again, would only be disposed of. Would you give this food to your family for Sunday dinner?
Poor Quality Pet Food Ingredients Revealed
Most of the "main stream", low cost dog foods may contain any of the following ingredients.
We could ramble on quite a bit longer but you get the picture.
Obviously, the commercial pet food industry is all about profit. Most commercial pet food companies are owned by huge national conglomerates who's names we won't mention due to legalities.
Great job guys! Buy cheap leftover, scrap animal parts, spoiled grains and fillers, mix in additives, spray it down with yummy tasting grease, and sell it to millions of families as food for their dogs. How would we know? Surely not by the plump chicken, fresh veggies and lean beef on the package, looks nutritious. Sadly, we should not be feeding Great Danes or any dog this over processed low nutritional value food.
