Cats and dogs evolved as hunters and despite a modern lifestyle, their digestive systems and internal anatomical features have remained unchanged for hundreds of years

Despite obvious and dramatic changes in their physical appearance, the basic physiology of the modern dog has changed very little with domestication. Today‘s modern dogs are not only capable of eating the food of their wild ancestors, but actually require it for maximum health. A biologically appropriate diet mirrors the same balance and variety of ingredients that would be consumed in the wild, including muscle meat, bone, fat, organ meat and vegetable materials.

Applied to dry foods, the Biologically Appropriate concept means higher-protein, moderate fat, low carbohydrate foods that contain high and various inclusions of animal ingredients that are processed as little as possible. Cereal grains are excluded and carbohydrates are reduced.

SUMMARY

Section I found that, despite obvious changes in their physical appearance, the basic physiology of the modern dog and cat has changed very little with domestication.

Section II asked the question of which foods are appropriate for their carnivorous anatomy, as well as which foods are not appropriate?

Conclusions are that dogs and cats are evolved as carnivores, and that despite obvious differences in appearance from their wild cousins, their internal anatomy remains unchanged.

  • Dogs are carnivores, not omnivores. Dogs ARE very adaptable, but just because they can survive on an omnivorous diet, does not mean it is the best diet for them.
  • With short digestive tracts and gastrointestinal systems, dogs and cats are adapted to metabolize animal flesh and fat, not grains and carbohydrates. 
  • Today‘s modern dogs (of any breed) are not only capable of eating the food of their wild ancestors, but actually require it for maximum health.
  • Biologically Appropriate foods are designed to match the digestive capability of dogs and cats. Just like the natural diet, they are high in protein and low in carbohydrates, with a concentration and variety of minimally processed meats and fats from animal source.

Although these findings are well accepted within the scientific community, conventional dry dog and cat foods appear to be created on the premise that the digestive system of the dog and cat is similar to humans - with a heavy emphasis on inappropriate grains and carbohydrates.

This leads to the next question:

If dogs and cats are carnivores, evolved for an almost exclusively meat-based diet, why do conventional pet foods contain such high levels of cereal grains and carbohydrate?

Section 3 – the History of Pet Foods attempts to answer.
