The Rational Behind Feeding a Raw Diet as opposed to Commercial Food
The domestic dog is descended
from the wolf, or a common ancestor, and is a carnivore. The wolf may
self medicate and eat some plant materials, but for the most part, it is
carnivore, eating whole prey, or parts of whole prey, and shaking out
and leaving stomach contents.
dog anatomically, is not evolved very much at all, other than to the
state of being able to survive as a scavenger, but still has the
digestive system of a carnivore, which has adapted somewhat to survive
as a scavenger also. It has the dentition of a carnivore, the strong
neck and jaw muscles designed for catching and pulling down prey, and
allowing no lateral movement of the jaw with only an up and down motion,
unlike herbivores and omnivores who have lateral movement in their jaws
have a highly elastic stomach, designed to hold large amounts of meat
and bone, organ and hide. They have a simple stomach, with an
under-developed caecum, with a short foregut, and a smooth, unsacculated
colon. This means that food passes through very quickly, whereas
vegetable and plant matter needs to have time to sit and ferment - thus
omnivores and herbivores have longer, sacculated colons, and longer and
larger small intestines, with the occasional presence of a caecum
(Feldhamer, G.A. 1999. Mammology: Adaptation, Diversity, and Ecology.
McGraw-Hill. pg 260.).
explains why unless vegetable matter fed to dog is
steamed/liquidised/mashed to break the cell walls; it will often come
out much the same as it went in.
have very little focus on canine nutrition in their training and often
make the mistake of viewing a dog as an omnivore, as advocated by
commercial petfood companies.
who has ever done canine studies will know the dog is a carnivore,
classified as a subspecies of the grey wolf, "Canis Lupus Familiaris".
a dog as if it were an omnivore places a large amount of stress on the
system, as other bodily organs have to work overtime to compensate; i.e.
the feeding of carbohydrates and starches places the burden of
digestion completely and entirely on the pancreas, as the dog does not
produce amylase in its saliva, so the pancreas has to produce unusually
large amounts of amylase to deal with the digestion of the starch,
cellulose and carbohydrates in plant matter.
also donot have the kinds of friendly bacteria that break down
cellulose and starch for them and as a result of this, most of the
nutrients contained in plant matter, even when pre-processed, are
unavailable to them.
is only due to the fact that some small evolutionary changes have
happened to enable dogs to survive as a scavenger that they have managed
to survive as long as they have on commercial, overprocessed diets
without more ill health than we already see, but the difference here, is
surviving compared to thriving, and obviously we want our dogs to
thrive, and not just survive.
facts explain why a dog is suited to a whole prey diet, or a diet where
the main make-up of whole prey is put together by the owner via chunks
of meat, bones, animal parts, organ meats and meaty bones.
To me the question of raw or cooked is common sense - after all, wild animals don’t cook !
and processed dog foods have only been around for about the last
100yrs, so not long enough for animals to have adapted to getting all
their goodness from what, to the internal system, presents as a
different form of food. On an evolutionary level, adaptations need much
more time than how long wolves and wild dogs have been living with
humans, as the changes would be from gross right down to molecular level
for the development of such different digestive capabilities.
There are several other aspects of a cooked, commercial diet, which cause problems, a couple of which I've mentioned below:
cooking food alters the proteins, fats and minerals, making some more
readily available, and others less available. Cooking also alters fats,
and many fats cannot take high cooking temps. and become rancid and
carcinogenic and toxic. Cooked proteins are also able to cause allergic
reactions, because of the changes cooking brings about, whereas raw
protein does not.
once food is cooked it is deficient in vitamins, minerals and enzymes,
since the act of cooking destroys or alters much of them; this is why
petfood manufacturers need to add synthetic supplements back into the
food - but finding the right balance is not easy by any means and is
infact incredibly difficult, as synthetic supplements donot always
exhibit the same form [chirality -three dimensional structure] that the
natural form has, which means their efficiency and use to the body are
substantially decreased. To compensate for this, the commercial foods
are ‘over-supplemented’ but this results in the inhibited uptake of
other necessary vitamins and minerals. For example, excess inorganic
calcium reduces the availability of iron, copper, iodine, and zinc
(Lonsdale, T. 2001. Raw Meaty Bones. pg 88). If you are feeding a
cooked, homemade diet, can you be sure that your pet's needs are being
sufficiently met if the very act of cooking destroys much of what is
beneficial to your pet?
once you cook your pet's food you are now guessing which vitamins or
minerals have been destroyed, how much of these might have been
destroyed (which means you would have to know how much was present in
the food in the first place), and how much supplementation your pet
how do we know that researchers have discovered all the nutrients
necessary for our pets? This still is an on-going process (such as
Eukanuba adding DHA to their foods; DHA is found in raw prey, so any dog
eating raw prey has been receiving appropriate levels of DHA), and
since cooking food destroys minerals and vitamins and enzymes,
researchers may be missing some very important nutrients. Feeding cooked
food also causes pets to miss out on these 'unknown' nutrients, whereas
raw food contains them in appropriate amounts.
raw food provides the added benefit of providing very necessary
teeth-cleaning for our pets, enabling us to avoid costly visits to the
vets where our animals are then subjected to trauma and anaesthetic
which is potentially harmful.
of the very harmful additives in commercially prepared dogfood is
Ethoxyquin - added as a preservative, because it gives the food a 2
yr shelf-life, much needed as food can be stored for as much as 18 mths
before finding it's way to the shop shelf.
fresh raw is what the internal make-up of the dog is most suited to
deal with, un-tampered with and purest and so best, providing the right
amounts of what is needed, in the right form and structure that the dogs
body can utilise and use most effectively.
and in a nutshell, why try and mess with the perfect design mother
nature had already set in place, and which has worked and still works
for our dogs wild cousins.
If anything, it is even more crucial
for our dogs these days to have a raw and fresh natural diet, because
their previous generations have been nutritionally starved on commercial
petfoods, and they need to have the type of diet most suited to them
biologically to prevent the illness and disease so many now suffer with
which. when traced, is down to nutritional deficiency going back
