Dogs
and Chocolate
by David the Dogman
Chocolate made for human consumption
can cause death in dogs. Dogs are sensitive to a class of chemicals
called methylxanthines. Caffeine and theobtomine are members of
that family. Dogs simply cannot metabolise and excrete methylxanthines
as efficiently as humans. The half life of those compounds in
the human body is in the order of 2 to 3 hours, in the dog it
is more like 18 hours.
In
a dog the compounds are taken up by the liver and transmitted
via the bile into the intestine. They are then converted back
into the original methylxanthines for another circuit through
the animal. This repeats itself a number of times and instead
of getting rid of the substances the dog keeps repoisoning itself.
There
are many formulations of chocolate with varying amounts of caffeine
and theobromine. The lethal dose of sweet milk chocolate for a
dog is 2 oz per kilogram of bodyweight. For a 5 kilogram dog this
would be about 280 grams. A lethal dose of milk chocolate for
a 25 kilogram would be about 1.4 kilograms.
Dark
chocolate is at least 10 times as lethal. A 25 kilograms dog could
die from the methylxanthines in 5 ounces.
Symptoms
include vomiting, hyperactivity, restlessness, hypersensitivity
to touch ( a dog will jump when touched very rapid heartbeat and
rapid breathing rate. A loss of control of leg muscles, muscle
tremor seizures, general weakness, coma and finally death follow.
In
my humble opinion it would be a tragic mistake to encourage a
dog to develop a taste for chocolate. A small dog left alone in
a house with a box of chocolates might well follow his nose to
the goodies and commit suicide by poisoning.
Commitment,
Firmness, but kindness.
