Poisonous Household Items, Foods, and Plants
Here is a list of every day house hold items that must be kept from your dogs
It is not chocolate itself that is poisonous to dogs, it is the theobromine, a naturally
occurring compound found in chocolate. Theobromine causes different reactions to
different dogs: dogs with health problems, especially epilepsy, are more affected by
theobromine than healthy dogs. Theobromine can trigger epileptic seizures in dogs
prone to or at risk of epilepsy. The size of the dog will also be a major factor: the smaller
the dog, the more affected it is by the same amount than a larger dog. Therefore, toxicity
is described on a mg/Kg basis.
Furthermore, theobromine can cause cardiac irregularity, especially if the dog becomes
excited. Cardiac arrhythmia can precipitate a myocardial infarct which can kill the dog.
Theobromine also irritates the GI tract and in some dogs can cause internal bleeding
which in some cases kills them a day or so later.
Theobromine is also present in differing amounts in different kinds of chocolate. Milk
chocolate has 44-66 mg/oz, dark chocolate 450 mg/oz and baking/bitter chocolate or
cocoa powder varies as much as 150-600 mg/oz. How much chocolate a dog can
survive depends on its weight (and other unknown circumstances). Under 200 mg
theobromine per kg body weight no deaths have been observed.
Theobromine will stay in the bloodstream between 14 and 20 hours. It goes back into the
bloodstream through the stomach lining and takes a long time for the liver to filter out.
Within two hours of ingestion, try inducing vomiting unless your dog is markedly
stimulated, comatose, or has lost the gag reflex. If your dog has eaten a considerable
amount of chocolate, or displays any of the above symptoms, take it to the vet without
In the absence of major symptoms, administer activated charcoal. The unabsorbed
theobromine will chemically bond to this and be eliminated in the feces. In pinch, burnt (as
in thoroughly burnt, crumbling in hand) toast will do.
Walnuts are poisonous to dogs and should be avoided. In particular, there is a type of
fungus common to walnuts (especially wet deadfall walnuts) that will cause severe
episodes of seizuring. Many nuts are not good for dogs in general, their high
phosphorous content is said to possibly lead to bladder stones.
Onions, especially raw onions, have been shown to trigger hemolytic anemia in dogs.

Anaemia Induced by Onion and/or Garlic Ingestion" - CM Edwards and CJ Belford

Potato poisonings among people and dogs have occurred. Solanum alkaloids can be
found in in green sprouts and green potato skins, which occurs when the tubers are
exposed to sunlight during growth or after harvest. The relatively rare occurrence of
actual poisoning is due to several factors: solanine is poorly absorbed; it is mostly
hydrolyzed into less toxic solanidinel; and the metabolites are quickly eliminated.
** Note that cooked, mashed potatoes are fine for dogs,
actually quite nutritious and digestible**
Turkey skin is currently thought to cause acute pancreatis in dogs.
It has recently been confirmed that grapes and raisins can cause acute renal failure in
dogs. The exact mechanism is not known, nor any means to determine the
susceptibility of an individual dog. However one vet  believes it may be an acute
auto-immune response to plant-borne viruses  in the same manner as FIP in cats.
While as little as one raisin can be fatal to a susceptible ten pound dog, many other
dogs have eaten as much as a pound of grapes or raisins at a time without ill effects.
The dog usually vomits a few hours after consumption and begins showing signs of
renal failure three to five days later.
