Human Foods that Poison Pets
Disclaimer
----------------------------------------------------------
Feeding pets food that we enjoy is not only wrong, it can also be fatal.
There are some foodstuffs that humans relish which cause illness and death
if eaten
by pets.
Chocolate, macadamia nuts and onions are good examples. Each of these foods
contains chemicals which rarely cause problems for humans, but for dogs,
these
same chemicals can be deadly.

Chocolate toxicity
Top
Chocolate contains theobromine, a compound that is a cardiac stimulant and a
diuretic.
When affected by an overdose of chocolate, a dog can become excited and
hyperactive. Due to the diuretic effect, it may pass large volumes of urine
and
it will be unusually thirsty. Vomiting and diarrhoea are also common. The
effect of theobromine on the heart is the most dangerous effect. Theobromine
will either increase the dog's heart rate or may cause the heart to beat
irregularly. Death is quite possible, especially with exercise.
After their pet has eaten a large quantity of chocolate, many pet owners
assume their pet is unaffected. However, the signs of sickness may not be
seen
for several hours, with death following within twenty-four hours.
Cocoa powder and cooking chocolate are the most toxic forms. A 10-kilogram
dog can be seriously affected if it eats a quarter of a 250gm packet of
cocoa
powder or half of a 250gm block of cooking chocolate. These forms of
chocolate contain ten times more theobromine than milk chocolate. Thus, a
chocolate
mud cake could be a real health risk for a small dog. Even licking a
substantial part of the chocolate icing from a cake can make a dog unwell.
Semi-sweet chocolate and dark chocolate are the next most dangerous forms,
with milk chocolate being the least dangerous. A dog needs to eat more than
a 250gm block of milk chocolate to be affected. Obviously, the smaller the
dog, the less it needs to eat.
Onion and garlic poisoning
Top
Onions and garlic are other dangerous food ingredients that cause sickness
in dogs, cats and also livestock. Onions and garlic contain the toxic
ingredient
thiosulphate. Onions are more of a danger.
Pets affected by onion toxicity will develop haemolytic anaemia, where the
pet's red blood cells burst while circulating in its body.
At first, pets affected by onion poisoning show gastroenteritis with
vomiting and diarrhoea. They will show no interest in food and will be dull
and weak.
The red pigment from the burst blood cells appears in an affected animal's
urine and it becomes breathless. The breathlessness occurs because the red
blood
cells that carry oxygen through the body are reduced in number.
The poisoning occurs a few days after the pet has eaten the onion. All forms
of onion can be a problem including dehydrated onions, raw onions, cooked
onions and table scraps containing cooked onions and/or garlic. Left over
pizza, Chinese dishes and commercial baby food containing onion, sometimes
fed
as a supplement to young pets, can cause illness.
Onion poisoning can occur with a single ingestion of large quantities or
with repeated meals containing small amounts of onion. A single meal of 600
to
800 grams of raw onion can be dangerous whereas a ten-kilogram dog, fed 150
grams of onion for several days, is also likely to develop anaemia. The
condition
improves once the dog is prevented from eating any further onion
While garlic also contains the toxic ingredient thiosulphate, it seems that
garlic is less toxic and large amounts would need to be eaten to cause
illness.
The danger of macadamia nuts
Top
Macadamia nuts are another concern. A recent paper written by Dr. Ross
McKenzie, a Veterinary Pathologist with the Department of Primary
Industries, points
to the danger of raw and roasted macadamia nuts for pets.
The toxic compound is unknown but the affect of macadamia nuts is to cause
locomotory difficulties. Dogs develop a tremor of the skeletal muscles, and
weakness or paralysis of the hindquarters. Affected dogs are often unable to
rise and are distressed, usually panting. Some affected dogs have swollen
limbs and show pain when the limbs are manipulated.
Dogs have been affected by eating as few as six macadamia kernels (nuts
without the shell) while others had eaten approximately forty kernels. Some
dogs
had also been given macadamia butter.
Luckily, the muscle weakness, while painful, seems to be of short duration
and all dogs recovered from the toxicity. All dogs were taken to their
veterinary
surgeon.
Be sure your pets can't get into your stash of chocolates, that food scraps
are disposed of carefully
to prevent onion and garlic toxicity and that your dog is prevented from
picking up macadamia nuts if you have a tree in your garden.

Foods to Avoid
Veterinary & Aquatic Services Department, Drs. Foster & Smith, Inc.
Q.
Which foods could be dangerous for my dog?
A.
A photo of various foods dogs should not eatSome foods which are edible for
humans, and even other species of animals, can pose hazards for dogs because
of their different metabolism. Some may cause only mild digestive upsets,
whereas, others can cause severe illness, and even death. The following
common food items should not be fed (intentionally or unintentionally) to
dogs. This list is, of course, incomplete because we can not possibly list
everything your dog should not eat.
Items to avoid
Reasons to avoid
Alcoholic beverages
Can cause intoxication, coma
<javascript:popupWin1('/dictionary_term.cfm?term=coma&cls=0',%2050,%2050,%20

Can contain onion powder, which can be toxic to dogs. (Please see onion
below.) Can also result in nutritional deficiencies, if fed in large
amounts.
Bones from fish, poultry, or other meat sources
