DOGS - A VEGETARIAN DIET?
But they need meat don't they?
You'll probably often hear people say "but dogs are carnivores, and
carnivores need meat." However, the true facts are not that simple.
Scientific studies have described the "all meat disease syndrome" in which
animals fed meat alone (without the addition of vitamins and minerals)
develop soft bones, general poor condition and sometimes die. The condition
is attributed to lack of adequate calcium, iodine and vitamins A and B1, and
to a poor calcium to phosphorus ratio. Meat is particularly deficient in
calcium. The natural diet is far more varied. Wild dogs and cats eat not only
the meat but also the bones (rich in calcium), the organs, and the intestines
containing assorted vegetable matter.
Why should dogs be vegetarian?
Even with government subsidies, the cost of meat is high in monetary terms.
To the cow, sheep, chicken, rabbit, pig or fish the cost is even higher: they
lose their lives, which in many cases will have been short, spent imprisoned
in intensive rearing conditions. Imported meat may come from countries where
slaughter methods are extremely cruel. It is indeed kind to save an unwanted
dog from destruction, but this to some extent loses its point if it means
that other animals will be killed to feed this one. Furthermore, eating meat
is a means of prolonging human suffering across the world. While half the
world is starving, we continue to rear animals for food, an inefficient means
of food production since only a small proportion of the food eaten by animals
becomes available as meat and dairy produce in the end. The yield of
essential nutrients from existing available land could be greatly increased
by growing plant foods for direct use.
Basic principles
If you are a vegetarian, you will already know about vegetarian foods. With
a little commonsense, your own meals can easily be adapted to suit the
animal. Give plenty of variety: deficiencies are unlikely if a wide variety
of foods are eaten. Find out what your animal does well on and what it
likes. Make meals appetising, taste and smell are especially important.
It is useful to remember that dogs are fond of yeast products so flavouring
with Marmite or Barmene might make food (such as Textured Vegetable Protein)
more attractive to them, as well as providing extra B vitamins. Dogs often
like a little honey for flavour, on cereals for example. At the same time,
check that you provide sources of all the various nutrients; protein,
carbohydrates, fats and oils, vitamins, minerals etc.
If the animal is thriving, then well and good. If there are problems such as
persistant diarrhoea, vomiting or itchiness, the animal may be allergic to
certain food items, so try to identify these and eliminate them from the
diet. However, occasional vomiting may be normal. Avoid strong, spicy foods
like curries. They tend to cause digestive upsets. When feeding cooked
foods, do not give them too hot. Nor should food be served too cold from the
refrigerator.
Remember that dogs have a shorter digestive tract than humans, and may not
cope so well with large quantities of fibrous (roughage) foods. However, they
do need their share of roughage (vegetables, bran, whole grain cereals, raw
fruit). Cooking fibrous vegetables (15 minutes at boiling) breaks down the
fibres, reducing the roughage value and making them more digestible but too
much cooking destroys some vitamins, especially thiamine. Crude fibre (ie
roughage) fills the gut to reduce feelings of hunger, and stimulates
defaecation, so some grated or chopped raw vegetables are useful in the diet.
Potatoes can cause digestive upsets in some dogs. Over-consumption of sugar
and sugary foods can encourage bad teeth, diabetes, digestive upsets and
obesity.
What they eat
Details provided by owners of vegetarian dogs living in Great Britain showed
that they liked and thrived on the following general feeding regime. This is
intended only as a general guide and should be adjusted to suit your animal.
ADULT DOGS
Dogs generally do well on two meals daily, a smallish breakfast and a main
afternoon or evening meal, though toy breeds may do better on three or four
smaller meals. Breakfast: (morning or midday)...usually wholegrain cereals
like muesli, Shredded Wheat, porridge in milk. Flavour with a little honey or
dried powdered yeast if necessary according to taste.
Dinner: (afternoon or evening)...a selection from the following:
(i) Grated cheese, cottage cheese, egg, nutmeat (tinned or home made),
textured vegetable protein, cooked lentils and other pulses, not forgetting
baked beans
TOGETHER WITH
(ii) Raw (grated or chopped) and/or cooked vegetables such as carrot,
cauliflower etc.
Other suitable foods
i) raw chopped or grated fruit, dried fruit.
ii) Wholemeal bread (fresh or toasted), Marmite sandwiches, baked rusk.
iii) Brown rice, sprouting grains.
iv) Remember that dogs need some hard foods to chew to exercise their gums
and jaws; perpetual sloppy food leads to dental tartar, pyorrhea and loose
teeth. Dogs can chew raw whole carrots, lightly roasted cabbage stumps, nylon
bones, raw whole apples, hard wholemeal dog biscuits.
v) Given daily, a teaspoon of uncooked vegetable oil such as sunflower seed
oil, by mouth or in the food (but unheated) for a medium sized dog such as a
cocker spaniel, or a few drops for a toy poodle, helps provide essential
fatty acids (polyunsaturates) to condition the coat. Vegetable oil should be
stored in a closed bottle in a cool, dark place (preferably a refrigerator)
to prevent oxidation of fatty acids. Oil may cause diarrhoea in a few dogs,
in such cases the quantity should be reduced.
PUPS
Birth to eight weeks
Pups generally depend solely on their mother's milk until around three weeks
of age. They continue to take the mother's milk until about seven or eight
weeks of age, but during this period they will supplement it with
progressively increasing amounts of other foods. Therefore from three weeks
(earlier if necessary) offer small dishes of milk, sometimes with baby
cereals or finely ground whole cereals as a slopy gruel (perhaps flavoured
with a pinch of dried brewers yeast powder to enrich B vitamins). A little
later, offer other foods from the list (i). Start with easily digested foods
like cottage cheese and poached egg. If certain foods cause serious
diarrhoea, avoid these. Feed small meals about five or six times daily as
young animals cannot digest large amounts at a time.
From eight weeks to about four months
Give four small meals daily. As a basic guide:
8.00am: Cereal in milk.
Noon: nutmeat and vegetables, egg, cheese, grated nuts, wholemeal bread
with Marmite or Barmene, fruit etc.
4.00pm: as 8.00am
8.00: similar to noon.
Also provide foods to gnaw as described earlier.
From four months to about eight months
Omit one meal, eg the 8.00am meal thus reducing to three somewhat larger
meals.
From about eight months onward
Feed as adult diet, usually two meals daily. Toy dogs often stay on three or
four meals daily.
How much to feed
This depends a lot on the individual animal. A very rough guide is given as 1
oz (30g) of total food per pound body weight for grwoing pups and 1/2 oz
(15g) per pound for adult dogs.
This rough estimate may be altered drastically by:
a) the liquid content of the food.
b) the calorie content of the food; a dog with a tendency to be overweight
can eat a lot of low calorie vegetables such as cabbage and cauliflower, but
much less of high calorie bread or cereals to produce the same calorie
intake.
c) individual variation: for example, some
highly-strung Alsatians require three to four times the calorie intake needed
by some Labradors the same size, or by some Alsatians with a lower metabolic
rate. The progress of the individual animal should always be the main guide
provided that a nutritionally balanced diet is fed.
Don't overfeed. A fat animal is not a healthy animal. If a dog is getting
fat, he is eating too much high calorie food. Watch the tidbits, they can add
up to a lot. By getting the animal to like low calorie vegetables from the
start, you will find it much easier to reduce his weight if necessary later.
In most cases, weight can be controlled by food intake control; only a few
are unslimmable "glandular" problems. Don't force a dog to eat if he doesn't
want to, you may be training him to get fat by so doing.
Final note
A perfect diet may be provided and yet the dog's health be spoilt because
insufficient exercise is given. Every dog needs plenty of exercise and fresh
air, EVERY DAY. Cleanliness is important and regular grooming is needed. For
long-haired breeds daily throrough combing is a must, otherwise matted hair
encourages skin disease and parasites. Lastly but very important, have clean,
fresh drinking water available at all times.
SOURCES OF NUTRIENTS
PROTEIN
Best sources: Cheese, eggs, soya beans, soya flour, tofu, TVP.
Other useful sources: Pulses (lentils, beans, split peas), whole cereals and
wheatgerm, sunflower seeds, sesame seeds, nuts except chestnuts and coconuts.
An assortment of protein sources provides a good balance of amino acids, eg
by feeding pulses and cereals together at one meal.
FATS AND OILS
Mainly saturated: butter, hard margarines, cheese, eggs, olives and olive
oil.
Intermediate: nuts, coconuts, wheat germ and their oils.
Mainly unsaturated: sunflower seed oil, safflower seed oil, corn oil, linseed
oil, soya oil, soft margarines which state high polyunsaturate content.
Dogs utilise unsaturated oils well. Vitamin E helps in unstaurated oil
metabolism. Unsaturated oils are oxidised, reducing their nutritional value,
by exposure to light, heat and air.
CARBOHYDRATES
Cereals and their products (flour, bread, cakes etc), bananas, chestnuts,
cashews, pulses, pears, dried fruit, potatoes, sugar etc.
Carbohydrates are unlikely to be in short supply in the average varied diet.
The startch in potatoes can cause diarrhoea in some dogs.
ROUGHAGE (CRUDE FIBRE)
Vegetables, bran and whole cereals, pulses.
VITAMINS
A:
i) as vitamin A--margarine, butter, milk, cheese, eggs.
ii) as the precursor carotene--carrots and green vegetables
In dogs, carotene has about half the nutritional value of actual vitamin A.
D:
i) As vitamin D--Margarine, butter, eggs, milk
ii) As its precursor, which is converted by sunlight on the animal's skin to
vitamin D - green leafy vegetables, cereal germ, yeast.
E:
Cereal germs (especially wheat germ oil), green leafy vegetables eg cabbage,
spinach, curly kale, lettuce.
K:
Green leafy vegetables.
B-COMPLEX:
except B12, yeast, whole cereals, cereal germs, bran, eggs, various
vegetables, nuts.
Easily destroyed by cooking.
B12:
Barmene, fortified soya milk, cheese, some TVPs (read the label!), milk.
C:
Fresh sprouts, curly kale, blackcurrants, rose hip pulp and syrup,
cauliflower, broccoli, cabbage, citrus fruits, strawberries, tomatoes, green
peppers.
Vitamin C is not normally essential for dogs as they synthesise their own.
However, some researchers suggest that vitamin C synthesis in dogs may be
inadequate on a low protein diet and a few individuals may not be able to
synthesise the vitamin and so require it in the diet.
MINERALS
CALCIUM:
Good sources - cheese, yoghurt, sesame seeds. Fair--almonds, black radish,
kolrabi leaves, dried figs, cucumbers, ripe beans, lemons, milk, tangerines,
leeks, curly kale, lettuce, cauliflower, endive, celery, peanuts, walnuts.
Foods with a good calcium/phosphate balance: cheese, yoghurt, ripe beans,
ripe peas, lentils, hens eggs, currants, curly kale, brussels sprouts,
kohlrabi, white cabbage, salsify, raisins, dried figs, milk, cauliflower,
celeriac, lettuce, dates, bananas, oranges, peanuts, almonds, walnuts,
hazels.
Low calcium relative to phosphorus: cereals and their products eg bread,
flour. These foods need to be balanced with higher calcium foods to prevent
calcium deficiencies. Phytic acid in cereals may also reduce calcium
absorption. Soaking grains overnight is believed to activate enzymes which
break down the phytic acid. Vitamin D is essential for calcium absorption.
IRON:
Celeriac, cream cheese, tangerines, spinach, various fruits, vegetables,
nuts, whole cereals.
IODINE:
seaweed eg kelp powder, eggs, whole grain rye and wheat, lettuce.
Other minerals are generally well provided in a diet containing a variety of
vegetables, fruit, nuts, milk cheese, eggs.
If your dog has been brought up on a meat diet, make the change-over to a
vegetarian diet gradual. With active dogs there is a problem of bulk versus
energy and readers are advised to consult their vet for guidance to ensure
that sufficient energy can be obtained from the mass of food given.
Milk alone is not an adequate source of calcium for puppies and a mineral
supplement of calcium phosphate is recommended. Rapidly growing dogs of
heavy breeds particularly need a high calcium intake.
See our Pet Care information sheet for details of ready made canned and dried
vegetarian dog foods.
