Myth "Dogs and cats are omnivores"

This is not true

Dogs are carnivorous, not omnivorous. Dogs adapt only because they can survive on an omnivorous diet, but this does not mean that this is the best diet for them. The assumption that dogs are natural omnivores needs proof, while the truth about dogs, which are natural carnivores, is very well supported by our facts.

1. Toothbed

Look at a dog or cat mouth. These huge impressive teeth (or tiny sharp teeth) are designed to grip, tear, grind and cut meat (Feldhamer, G.A. 1999. Mammology: Adaptation, Diversity and Ecology. McGraw-Hill. Pg 258). They are not equipped with large flat molars for grinding vegetable matter. Their molars are pointed and located in the bite of scissors (along with the rest of their teeth), which are powerfully straightened with meat, bone and skin. Carnivores have a special set of teeth, which include the presence of carnival teeth: the fourth upper premolar and the first lower molar.
This is the weasel skull (also in the order of Carnivora), kindly provided by the Centennial Museum. Carnival teeth are marked with black arrows. You can find these teeth in the mouth of your dog or cat or ferret.

Compare this with your own teeth or the black bear's teeth. The black bear is a true omnivorous, just like us. We have good, big, flat molars that can chop vegetables. Black bears, having impressive fangs, also have large flat molars in the back of the mouth to grind vegetative matter. Dogs and most predators lack such molars. Why? Because they do not eat plant matter. The teeth are highly specialized and structured specifically for the diet that the animal eats, and the difference between bear teeth and dog teeth (both species are carnivores) demonstrates how this can be (Feldhamer, GA 1999. Mammology: Adaptation, Diversity, and Ecology. McGraw-Hill. Pgs 260.). To see a visual comparison of a dog’s teeth with a black bear’s teeth, click here. One can logically ask: if a dog (or a cat or a ferret) has a dentition of a carnivore, why do we feed it with granulated, bread feed?

2.) Musculature and external anatomy

Dogs (and cats) are equipped with powerful muscles of the jaw and neck muscles, which help to pull out prey and chew meat and bones. The hinges of their jaws are wide open, which allows them to swallow large pieces of meat and bone. Their skulls are heavy and have a special shape to prevent lateral movement of the lower jaw during contractions with the prey (the lower jaw is deep and C-shaped); this form allows only upward and downward crushing, whereas herbivores and omnivores have a flatter lower jaw, which allows lateral movement necessary for shredding plant matter (Feldhamer, GA 1999. Bremmology: adaptation, diversity and ecology. McGraw-Hill pgs 258-259.). Consider this quote from the previously quoted text of mammology: “Canids, felids, and gophers exist mainly on the recently killed victim. These families, respectively, significantly develop the "tooth and claw", they also develop more carnasian development and cursorial locomotion. " (pg 260) This speaks of a simple fact: everything in the body structure of a dog or cat says that they are intended for a carnivorous, hunting way of life, aimed at killing prey. Nevertheless, people did some major manipulations with this body design (leading to different sizes and configurations), but we did nothing to change the internal anatomy and physiology of our carnivorous dogs.

3.) Internal anatomy and physiology

Dogs and cats have an internal anatomy and physiology of carnivores (Feldhamer, G.A. 1999. Mammology: Adaptation, Diversity and Ecology. McGraw-Hill. Pg 260.). They have a very elastic stomach, designed to store large quantities of meat, bones, organs and skins. Their stomachs are simple, with an undeveloped cecum (Feldhamer, G.A. 1999. Mammology: Adaptation, Diversity, and Ecology. McGraw-Hill. Pg 260.). They have a relatively short cutting edge and a short, smooth, restless colon. This means that food passes quickly. However, the plant matter takes time to digest and ferment. This equates to longer, mesh bags, larger and longer small intestines, and sometimes the presence of the cecum. Dogs do not have any of them, but have shorter fore and hind limbs consistent with carnivorous animals. This explains why plant matter comes out the same as it was; there was no time for its destruction and digestion (by the way). People know this; that is why they tell you that vegetables and grains must be pre-processed for your dog to get something from them. But even then the feeding of vegetables and cereal carnivorous animals causes doubt.
