Experts have been arguing for years about whether domestic dogs are technically omnivores or carnivores. Some experts consider dogs to be strictly carnivorous, while others consider them omnivores as their digestive tracts can process plant foods. Based on the adaptations of their digestive tract, I believe that dogs are carnivorous scavengers, while cats are real predators.
For this reason, some experts refer to dogs as "meat scavengers" rather than true predators. However, many people believe that dogs are carnivores because wolves are their ancestors and eat meat. Modern dogs are direct descendants of wolves and are vivid examples of true predators.
Evidence for omnivory is evident when dogs are compared to true carnivores. However, it must be recognized that dogs also have remarkable omnivorous abilities. There are many innate behaviors that dogs exhibit that is closer to carnivores than omnivores or herbivores. Although dogs are considered optional predators, they are not actually omnivores.
Although they differ somewhat from cats, dogs should be considered carnivores based on their set of teeth and canine length. Dogs can only survive on plant material and are comfortable eating combinations of meat and non-meat foods. This means that while dogs need meat to survive, they can also benefit from plants in their diet.
At the end of the day, dogs can thrive on a plant-based diet, but some dogs may prefer meat. In fact, dogs can be omnivores—after all, they can thrive on a mostly plant-based diet. Because dogs can eat non-meat foods, some believe this makes them omnivores. Of course, this doesn't prove that dogs can't eat plants, but it does suggest that dogs can't get all their nutrients from sources other than meat.
This is less of an argument that dogs are omnivores than a possible explanation for why so many people think they need plants and grains in their diets. In fact, dogs are omnivores, and even wolves in the wild get their food from plants and animals. Despite surviving, omnivorous humans have fed dogs an omnivorous diet rich in plant-based protein sources such as corn and rice for many years. Dogs are actually omnivores, and a balanced omnivorous diet includes a combination of meat and plant-based foods.
Even if dogs show remarkable omnivores, we consider it important to give preference to meat products. Because omnivores thrive when their diet contains meat and plants, it's best to have a balanced diet for your dog.
If you feed your dog raw food, it should be mostly meat and not other foods. The most important part of dog nutrition is to provide your dog with a complete and balanced diet, whether or not the complete diet includes meat as its main source of protein. Meat is a great source of protein for most dogs, but it's not the only ingredient a puppy needs in its diet. A balanced diet that meets a dog's nutritional needs includes meat and plant-based foods, provided that the diet consists of high-quality ingredients and includes essential protein and fat.
Conventional wisdom says that dogs are omnivores, which is why commercial dog foods are high in fruits, vegetables, and grains in addition to meat. Dogs not only eat non-animal food, but they are also able to process and absorb nutrients such as those found in grains, legumes or fruits. However, dogs are known to require certain nutrients from animal meat for proper metabolism. When dogs were first domesticated, they developed some digestive and metabolic characteristics that led many scientists to classify them as omnivores.
These traits, inherited from their dogs, allowed them to become omnivores. However, once the dogs we see today began to be associated with humans, the dog's diet changed dramatically from almost exclusively carnivorous to more omnivorous. Centuries of pet dog feeding have shown that dogs can live healthy lives on an omnivorous diet.
Despite the natural carnivorous nature of dogs, dogs have still managed to evolve over the millennia...surviving off the remnants of meat and non-meat, and the remnants of human existence. Of the three main dietary categories of animals—carnivores, herbivores, and omnivores—we know that dogs are absolutely not herbivores. While no one disputes the fact that dogs primarily eat meat or the fact that they seem to prefer meat over other food sources, it has only recently been argued by some experts that they may be obligate carnivores, just like cats.
Anyone who tells you he's an omnivore has a cheap reason to call a dog an omnivore, usually because they sell high-carb diets that aren't really suitable for an optional carnivore. Do you know how you know that your dog is not omnivore and is actually somewhere between an omnivore, human or pig where we can eat anything, or an obligate carnivore where it has no amylase and cannot digest carbohydrates and actually interferes with the proper digestion of obligate carnivorous carbohydrates?
Cats have noticeably smaller intestines, which is part of the biological reason they are considered obligate carnivores that require meat to make up the bulk of their diet, but dogs are also physically adapted to easily digest plants. This does not mean that omnivores cannot eat plants, as any dog owner who watches their pet eat grass can attest.
