Nature has fed us and all animals on earth for millions of years. As far as I can tell nature has been very successful with the millions of animals which have evolved and flourished. Why is it then when we feed our pets we are to break away from the nature feeds them and we are encouraged to only feed them commercially processed foods. We know for our diet to be complete we need to eat a wide variety of foods which are calorie controlled but offer maximum nutrition, a true wholistic diet. There aren't many people who have taken nutrition courses to study our diet to ensure every meal we eat is completely balanced. More of us are reading about how to feed ourselves better, and everyday one can learn something new on making our diet healthier. I seem to be learning more everyday. The one thing that has always held true is the more variety of foods we consume from the major food groups throughout our entire life along with maintaining physical exercise we should be able to live a life which is active and healthy. I believe our pets should be fed the same way. The main difference is they require more meat in their diet and require less. Dogs and cats are carnivores. Their anatomical make-up is identical to their wild relatives. Our domestic dogs and cats internal make-up has not changed in the short evolutionary time we have cared for them. Yes, there are many different kinds and sizes of dogs and cats but thi is true in nature as well. Look at the many types of wild cats around the world from lion to ocelots - they all consume essentially the same diet; meat. Dogs in the wild world are little more adaptive than cats are. Dogs during World War II successfully bred and survived while consuming mostly vegetable based foods. Although generations of dogs on this veg based diet would certainly display developmental issues. Domestic dogs display their scavenging tendencies everyday. Most people who have been owned by a dog have witnessed their dogs scavenging through garbage, eating fecal matter (we liked to call them poopsicles), vomit and many rotten goodies found in your back yard or while on their walk. Most of these behaviours are not usually approved by their humans. I hear it everyday in the store. Is my dogs food missing something? He keeps eating his stool. I am not endorsing a diet of fecal matter, and you won't ever see me offering packaged "poopsicles". Although it would probably make the evening news if I did! Reason dogs do this is for the same reson rabbits do and many other animals in this world do. Their are enzymes and phytonutrients in fecal matter which act as catalysts for many functions in your dogs body. Again I am not encouraging you to push this food group on your pet, all I am emphasizing is that as a human yoou shouldn't worry about this behaviour, it is normal for a dog. Although, I would keep this in mind the next time your dog "gives you a kiss"! The purpose of this discussion is to encourage you to think a little outside of the box, at least the box pet food companies want us to stay in. Their bottom line is their first concern.
