Five years ago, I published a list of 13 types of pet foods ranked from best to worst. That video remains one of the most popular here at Mercola Healthy Pets as well as on YouTube. There have been a few updates since I made that video, so I thought it was time to publish a new revised list.
[h=2]When Deciding What to Feed Your Pet, Remember: Your Dog or Cat Is a Carnivore[/h]
First and foremost, when you're deciding what to feed your dog or cat, it's important to remember that your pet is a carnivore. His genetic makeup and internal workings remain essentially the same as his wild carnivorous ancestors.
Your dog or cat can't move his jaws from side-to-side, only up and down. That's because carnivores grab their prey, tear it into chunks with their sharp, interlocking teeth, and gulp it down without chewing.
Omnivorous mammals (for example, humans) have sharp teeth plus wide flat molars designed for chewing. Vegetarian animals have mouths full of wide, flat molars designed for excessive mastication (a lot of chewing). In fact ruminants, for example, cows, actually chew their food twice.
All carnivores, including dogs and cats, have very short digestive tracts compared to vegetarian animals. This is because nature designed carnivores to be able to eat foods that are heavily contaminated with pathogens. Wild dogs and cats don't remove the colon or other bacteria-laden body parts from prey animals before they eat them.
So, their digestive tracts are designed to get food in and out very quickly to limit exposure to pathogens. A carnivore's digestive system isn't designed to ferment foods like the GI tracts of vegetarian animals.

The ancestral diet of a carnivore includes lots of variety and seasonal variability because certain prey is more available at certain times of the year. Wild dogs and cats thrive by consuming fresh, living whole foods. The food is moisture-dense because prey animals are about 70 percent water, plus it's high in protein and minerals, and moderate in fat.
There are no obese rabbits or other small prey animals in the wild, which is why dogs and cats do best with a diet containing moderate to low amounts of high quality animal fat and a very low percentage of carbohydrates.
The only carbs wild cats consume are what is naturally found in the gastrointestinal tracts of their prey, plus the occasional nibble of grass which provides added fiber and enzymes.
Wild dogs (including wolves) are scavenging carnivores, so their diets are more varied than wild cats. Like cats, they catch, kill, and consume whole prey, but they also eat carrion (dead animals). You'll never see a cat going anywhere near a dead animal as a food source.
Wild dogs also eat poop, grass, berries, and other plant matter. In fact, research shows that up to 30 percent of the stomach contents of wolves contain plant matter.

Commercial pet food is a relatively recent development, having been around only about 100 years. During that time, major pet food companies have produced most of their products using a base of corn, wheat, or rice.
However, they are now recognizing that feeding carnivores an abundance of grains causes cancer and creates fat, diabetic animals, so the industry is turning to grain-free dry foods. This move has re-ignited the popularity of kibble, but the problem is that biologically inappropriate levels of high-glycemic starches like potatoes and pea flour have taken the place of grains in dry pet food.
Another recent development is the use of trendy sources of carbs in pet food, for example, lentils and garbanzo beans. However, in addition to increasing the carb content beyond what is species-appropriate, legumes contain lectins, which are molecules that can create GI inflammation and irritation.
Fortunately for pet owners, dogs and cats are among the most resilient animals on the planet. They're able to survive when fed foods they were never designed to eat.
However, degeneration does occur in these animals as a result of inappropriate nutrition. But because the changes are gradual and often hidden until a disease is full-blown, we've been able to deceive ourselves into believing that convenience pet foods are actually good for dogs and cats. But in my opinion, we've created dozens of generations of nutritionally compromised animals that suffer from degenerative diseases linked to nutritional deficiencies.
