KIBBLE + RAW ?!?
Why Not Feed Kibble AND Raw ?

So, Should Kibble be Mixed with Raw ?
The short answer is No, the long answer follows.
a perfect world, no dog would be subjected to eating carbohydrate
laden, enzyme-less, dead and nutrient deficient kibble. They’d be eating
the nutrient rich, moisture drenched, whole carcasses of animals such
as deer, rabbit and pheasant etc., or the next best thing, raw meaty bones.
Kibble (all of it) contains carbohydrate either in the form of grains (wheat, rice, oatmeal etc.) or starches (potato, pea). According to the “guaranteed analysis” of Orijen’s Regional Red Meat, it contains a maximum of 22% carbohydrate. With Orijen considered a “premium” brand, I think it’s safe to say that most kibble on the market contains at least 25% carbohydrate.

is no known minimum dietary carbohydrate requirement for either the dog
or the cat. Based on investigations in the dog and with other species
it is likely
that dogs and cats can be maintained without carbohydrates if the diet
supplies enough fat or protein (editors note: raw meaty bones) from which the metabolic requirement for glucose is derived.”

“Dogs have little evolved need forcarbohydrates
and cats have no need for this source of energy. Consequently these
species produce low levels of digestive enzymes required to deal with
the high starch content. So right out of the gate mixing kibble with
raw, or even feeding kibble at all for that matter, doesn’t seem like
such a great idea."
A Couple of Reasons Why You May Not Want to Feed Kibble
and Raw Concurrently
A dog’s digestive system is short (compared to omnivores and herbivores) and is designed for the quick transit though of raw meat (sometimes rotting) and bone.
short digestive system along with a highly acidic stomach means that
potentially harmful bacteria (salmonella & E coli) and other
microbes have little time to take up residence and proliferate and cause
health problems for the dog.
A much longer digestive tract like those found in omnivores and herbivores is required to ferment and digest carbohydrate.
It would seem logical that since carbohydrate laden kibble contains no live enzymes to assist in digestion, that digestion would be more difficult as compared to a strictly raw meat and bone meal, and that the digestion of kibble would require more time.
Slower motility of the mixed kibble/raw meal through a dog’s GI tract would increase the length of time that pathogens could take hold along the dog’s GI tract, thereby increasing the risk of illness to the dog.
also seems logical that eating an enzyme-less, dead kibble would
require a dog’s pancreas to work harder in order to produce more
digestive enzymes to digest the excessive carbohydrates contained in the
kibble, and perhaps lead to diabetes or pancreatic insufficiency later
in the dog’s life.
“Slowly or poorly digested material tends to damage the bowel lining.” – Raw Meaty Bones Promote Health
can occur by direct physical or chemical action of the food on the
bowel. More commonly the damage is due to a change in the resident
population of bacteria as a result of the poorly digested material.
Harmful bacteria and their toxins affect the lining of the bowel, and if
absorbed into the blood stream are harmful to other organs. With an
increase in harmful bacteria there is a corresponding decrease in
helpful bacteria.”– Raw Meaty Bones Promote Health
