Why not to feed raw and kibble/wet food/Carbohydrates...

I'm writing this to dispel the myth that its OK to feed both a raw food diet and a kibble or wet food diet, or carbohydrates. (please note: what you do is your choice of course, but it doesn't mean we recommend doing it).

IT IS NOT OK and here is why we do not recommend it. It is not because 'kibble takes longer to digest than raw', it is MUCH MORE than that!

First of all, kibbles and wet food contains carbohydrates in some form (do not fall into the trap of grain free food - grain free does not mean carbohydrate free). They almost always contain potato, sweet potato, and other starches. These carbohydrates found in the kibbles/wet foods have an affect on your dogs stomach in many ways. One of the main things is that it affects your dogs stomach pH, making it a more neutral environment (pH 4-5), rather than it's natural acidity of pH 1-2. Dogs NEED this natural acidity to be able to effectively and safely digest and utilise the raw meats, and to be able to kill off most bacteria, including Salmonella and E-coli. Salmonella can begin to grow in a environment where the pH is 4. Even if a kibble or wet food was fed in a separate meal... it still affects the dogs stomach acidity, which is why most raw feeding guides suggest starving dogs for X amount of hours before beginning their new diet. 

Also, the mucus in the lining of the stomach is designed to 'trap' the bacteria so it can be killed before it transits to the rest of the gut. Carbohydrates in the diet prevents the dogs stomach from expanding properly to be able to release Gastrin and Hydrochlauric Acid to be able to kill them, and digest the raw protein. Particularly, the added salt in the food can damage the mucus on the lining of the stomach.

Other things also happen within the dogs stomach if you are willing to risk feeding both kibble and raw... it decreases the production of Pepsin meaning a slower digestion of protein, and it increases the transit time to digest and absorb the protein. This is not good for the simple reason that raw meat is mean't to digest fast in a canines stomach for a reason. Slowing down the digestion means more time for bacteria to multiply, and on top of that the stomach acid isn't strong enough to kill them like said above. It's never a good idea to have raw meat stuck inside a dogs gut when it's not at it's optimal levels.


What does this mean? YOUR DOG HAS A HUGELY INCREASED CHANCE OF BACTERIAL INFECTION. Is it worth the risk, really?

The addition of carbohydrates (in the form of kibble and wet foods), do even more damage! It has been found by Theodore Van Italie of Columbia University, that when carbohydrates in the diet are consumed they can cause Vitamin C depletion.  Vitamin C deficiency could be a by-product of processed, carbohydrate laden diets. Nutritionists Julie Will and Tim Byers of the Centers for Disease Control and the University of Colorado respectively found  high blood sugar and/or high levels of insulin work to increase the body’s requirements for vitamin C. When blood sugar levels are increased by carbohydrates in the diet, the cellular uptake of vitamin C will drop. High levels of blood sugar will also impair the reabsorption of vitamin C by the kidneys, so the higher the blood sugar, the more vitamin C will be lost in the urine. Dogs Naturally Magazine suggest that the consumption of carbohydrates might not only affect their stomach but prevent them from being able to gain and utilise the vitamins in the raw meat.
