Whatever
dog food you use, whether it be canned dog food or
complete dog food, the basic principle to be understood
in the feeding of dogs is that, with only minor variations,
they have the same nutritive requirements as man.
These days you can even get a variety of vegetarian
dog food at reasonable prices. A dog apparently has
less need for starches, and its digestive juices do
not handle fatty foods well. Thus, the dog's meat
should always be quite lean, otherwise it will commonly
cause a stomach upset with symptoms of vomiting and
diarrhea.
The
best foods for the dog are milk, meat, and vegetables.
Most dogs will enjoy milk and digest it readily. Some
breeds, however, such as the Boston Terrier, often
do not seem to be able to handle milk and will vomit
it. Where this occurs, milk should naturally be avoided.
But with most breeds this difficulty will not be encountered.
With a little experience the individual dog owner
can determine what the situation is with his particular
animal. In regard to meat: beef, lamb, or horsemeat
are generally considered best, while pork is usually
not recommended.
Lamb
or horsemeat are best served cooked, while beef may
be fed either cooked or raw. Whether meat is fed cooked
or raw depends both on convenience to the owner and
on the preference of the animal. It will make no difference,
however, to the health of the dog which way the food
is fed. As far as vegetables are concerned, most dogs
generally handle them quite well. However, as with
milk, the owner will have to determine on the basis
of actual experience which vegetables the animal prefers
or which it can properly digest.
In
most cases, diced lettuce and tomatoes will be found
to be the most readily accepted. Dog owners often
raise the question of the egg requirements for their
dogs, mentioning that they have heard somewhere that
the feeding of eggs will encourage a glossy coat.
This belief is incorrect. Vigorous dogs that are properly
cleaned and groomed will have glossy coats whether
or not they have ever been fed eggs.
Unhealthy dogs, or those that are improperly cleaned
or groomed, will not have a good, shiny coat no matter
how often eggs are fed. Eggs, however, are a perfectly
wholesome food for dogs and are an excellent source
of protein. But, since meat and milk are equally rich
in this nutrient and are generally cheaper, eggs are
usually considered to be a good, though uneconomical,
supplementary food for dogs. As for the tremendous
variety of dry or canned commercial dog foods, most
animals will get along perfectly well on them, though
it is often suggested by the most competent authorities
that the best results will be obtained if dog foods
are fed only in combination with fresh foods.
Great
strides have been made in the improvement of commercial
dog foods in recent years. Their formulae are specially
prepared by trained scientists to meet all of the
dog's needs, and all nationally known brands are guaranteed
by the federal government, on the basis of careful
experiment, to furnish normal maintenance diets. This
means that the dog can live its entire life without
eating anything but dog food. For those owners within
the low income brackets, or those with the very large
breeds, the feeding of dog food exclusively would
certainly be the most economical method and, as far
as the dog is concerned, such a diet is quite adequate.
Something
should also be said of the great variety of commercial
dog biscuits. While some companies will claim that
their biscuits are a complete food, and are often
justified in their claim, most experts agree that
the large majority of the biscuits that are manufactured
serve best only as a supplementary food. They may
be fed dry, but usually are preferred by dogs when
mixed with meat and broth. If biscuits are fed, then
the feeding of vegetables is usually unnecessary,
because the essential elements contained in vegetables
are present in most biscuits.
Bones
are not essential to the health of the dog. The food
elements contained in bones are already present in
other foods that are routinely fed. True, the dog
loves bones. He particularly enjoys the bone marrow
and relishes it with the same enthusiasm that a child
does candy. However, bone chips may lodge in the throat,
scratch the delicate membranes that line the digestive
system, or otherwise be the source of considerable
annoyance. So to maintain the health of the pet it
is best to deprive it of this pleasure. If the owner
feels badly about depriving the dog of a bone, then
the least harm can be done by letting the animal play
with a small section of one of the large leg bones
of an ox. Usually these bones are so thick that the
ordinary dog can only toy with them and not chew them
to bits. But the teeth and jaws of many dogs are so
strong that they can mutilate almost any bone. In
such cases, the feeding of bones can do nothing but
harm.
The
trait of burying bones is an instinct acquired in
ancient times when a dog was compelled to do so to
make sure of a future meal. It is not true, as has
sometimes been suggested, that the dog did this because
he preferred his meat "ripe." The fact is that the
dog prefers his food fresh and will resort to stale
food only when fresh food is not available. The dog
of long ago buried food simply as a security measure
so that he could have something to come back to when
fresh food was lacking. The modern dog still buries
bones, but he does so by force of ancestral habit.
He will dig them up only when insufficient fresh food
is forthcoming. If he is well fed he will ignore his
buried treasure.
Most
people have peculiar ideas about the feeding of candy
or any other form of sweets. It is a common belief
that sweets will cause worms in dogs. This is not
true. It is another common notion that sweets, in
any form or quantity, are bad for dogs. The fact is
that when sweets are fed in moderate quantity they
will do no more harm to the dog than they will to
the human. The question logically follows: how much
is a moderate quantity? The best answer is simply
that the dog should be permitted to have an occasional
nibble of candy, let us say, as a reward for especially
good behaviour. If the dog is restricted to this occasional
nibble, no harm can result.
Of
course, if the dog never has candy, it never will
be missed. However, sweets comprise one of the good
things of life. To have a wee bit once in a while
is a simple and modest pleasure. There is no point
in depriving the animal of it. In addition to the
regular food, dogs, during the first year of life,
should be fed some vitamin supplement to assist in
the proper development of the bones and the eyes.
This can be done by giving about half a teaspoon of
cod-liver oil a day to animals weighing less than
twenty pounds, and a full teaspoon to animals over
twenty pounds. The very large breeds may be fed as
much as two teaspoons a day. If tablets are preferred,
the ordinary "one-a-day" vitamin preparations that
can be bought at any pharmacy will usually serve admirably
when given to the dog weighing twenty pounds or more
in the same dosage as is given to man.
Smaller
dogs are given proportionately smaller doses. Before
making an explicit statement of the practical feeding
routine, it would be well to mention a few words about
the eating of grass. The ancestral dog probably ate
grass when he was nauseous, toxic, constipated, or
otherwise indisposed. The grass would exercise a beneficial
laxative effect, causing the animal to vomit and to
move its bowels, accompanied by relief of the indispositions.
This seems to have been a wholly instinctive activity;
the modern dog has retained this instinct. It still
eats grass and apparently does so for the same reason
as the ancestral dog. However, while the eating of
grass does actually have salutary effects on many
vigorous modern dogs, it also often produces harmful
effects on a goodly percentage of animals maintained
as household pets. It commonly causes an inflammation
of the lining membranes of the stomach and intestine,
with resulting vomiting and diarrhea that persist
until the grass eating is stopped.
Apparently
many generations of domestication have wrought a change
in the modern dog, at least to the extent that its
body often can no longer withstand the violent cathartic
action of grass. The dog owner can determine on the
basis of experience just what the effect of grass
on his particular animal happens to be. If he finds
that grass does no harm, or is even helpful to his
animal, he can allow this activity. If he determines
that grass is harmful to his animal, he should naturally
make a special effort to curtail the ancestral habit.
Finally,
a popular prejudice may be debunked. It is a common
belief among dog owners that liquor will stunt the
growth of a dog. The truth is that liquor will not
affect the growth of a dog any more than it will influence
that of a human being. Dogs may be taught to drink
intoxicating beverages, and if they take them in small
or moderate quantities no harm will usually result.
But it is also a fact that most dogs seem to have
a violent revulsion to liquor, and to train an animal
to drink it would be a rather difficult task. In any
case, the feeding of liquor to the normal dog serves
no useful purpose.
Sometimes, when the animal is quite sick, liquor may
be useful for medical purposes because of its qualities
as a stimulant. Its medicinal use, however, should
always be left to the discretion of the veterinarian.
The quantity of food to be given should not cause
undue concern. Some dogs, like some people, are bigger
eaters than others. The least amount of food that
will maintain the animal in vigorous condition is
the most desirable. If the animal appears too fat,
cut down somewhat on the food. If the animal appears
too thin, then feed larger quantities of food. If
you are in doubt, ask your veterinarian. The practical
feeding routine varies with the age of the animal.
