Dogs Are Carnivores
The large dog food manufacturers spend millions trying to convince you that dogs are omnivores, but it's just not true.
Dogs are members of the Canidae family of the mammalian order Carnivora. To put it simply, they are supposed to eat meat.
Many of the dog food companies try to tell us that it's natural for dogs to eat vegetables. They also claim that wolves eat the stomach contents of their plant-eating prey. But many experts say this isn't true.
L.David Mech is a wildlife research biologist who for over 30 years has studied lage carnivores, especially wolves and their prey. Mech is considered to be the world's leading wolf biologist. In his 2003 book Wolves: Behavior, Ecology and Conservation, he writes:
"Wolves usually tear into the body cavity of large prey and...consume the larger internal organs, such as lungs, heart, and liver. The large rumen [, which is one of the main stomach chambers in large ruminant herbivores,]...is usually punctured during removal and its contents spilled. The vegetation in the intestinal tract is of no interest to the wolves, but the stomach lining and intestinal wall are consumed, and their contents further strewn about the kill site." (pg.123, emphasis added)
"To grow and maintain their own bodies, wolves need to ingest all the major parts of their herbivorous prey, except the plants in the digestive system." (pg.124, emphasis added).
The dog food companies are just trying to make us believe this so they can use cheap filler like corn, soy, wheat, and even peanut hulls in their food.
Let's just look at the science.
If we look at the dogs physiology, it tells the whole story.
Teeth: Sharp, pointy, and scissor-like, ideal for tearing flesh and crushing bone. Not flat, like the molars of cows and bears, which are used for grinding plant matter.
Saliva: They have no amylase in their saliva. Herbivores and omnivores produce this enzyme to help break down vegetation.
Digestive Tract: Dogs have a very short and acidic digestive tract, ideal to process meat and bone. Not nearly long enough to get any nutritional benefit from vegetables.
Dogs have the internal anatomy and physiology of a carnivore. When an independent expert (NOT paid by a dog food company) with 30 years experience tells me that a dog is a carnivore, I'm inclined to believe he knows what he's talking about.
