Poisons and other toxins

Alcoholic Beverages

Alvocado

Antifreeze
is highly poisonous. Unfortunately, dogs actually like the taste of the stuff. Don't leave even a little on the driveway and never
leave an open container where pets can reach it.

Aspirin, in appropriate doses is ok for dogs (not cats), but do not give Advil, Tylenol, or any other pain killer without specific instructions
from a veterinarian.

Batteries

Chocolate
contains theobromine. A naturally occurring stimulant found in the cocoa bean, theobromine increases urination and affects the
central nervous system as well as heart muscle. While amounts vary by type of chocolate, it's the theobromine that is poisonous to dogs.   
Symptoms of Chocolate Dog Ingestion and Poisoning:
You can recognize that your dog has eaten a toxic dose of chocolate from the symptoms. Within the first few hours, the evidence includes
vomiting, diarrhea or hyperactivity. As time passes and there's increased absorption of the toxic substance, you'll see an increase in the
dog's heart rate, which can cause arrhythmia, restlessness, hyperactivity, muscle twitching, increased urination or excessive panting.
This can lead to hyperthermia, muscle tremors, seizures, coma and even death.
How much is too much?
  • White chocolate: 200 ounces per pound of body weight. It takes 250 pounds of white chocolate to cause signs of poisoning in a 20-
    pound dog, 125 pounds for a 10-pound dog.
  • Milk chocolate: 1 ounce per pound of body weight. Approximately one pound of milk chocolate is poisonous to a 20-pound dog; one-
    half pound for a 10-pound dog. The average chocolate bar contains 2 to 3 ounces of milk chocolate. It would take 2-3 candy bars to
    poison a 10 pound dog. Semi-sweet chocolate has a similar toxic level.
  • Sweet cocoa: 0.3 ounces per pound of body weight. One-third of a pound of sweet cocoa is toxic to a 20-pound dog; 1/6 pound for a
    10-pound dog.
  • Baking chocolate: 0.1 ounce per pound body weight. Two one-ounce squares of bakers' chocolate is toxic to a 20-pound dog; one
    ounce for a 10-pound dog.

Coffee (all forms of coffee)

Christmas tree preservative

Fatty foods

Human cough/cold/flu medications

Liquid potpourris

Macadamia nuts

Moldy or spoiled foods

Mushrooms
can cause severe illness or death. Try to keep them cleared away from places your dog can reach.

Oleander, Poinsettias, Mistletoe, American Holly, Acorns and other poisonous plants make puppies pretty sick, but the quantities eaten
are usually not life-threatening.
Some flower bulbs are highly poisonous and dogs will occasionally be fatally poisoned by eating them.   
Most dogs won't do this, but it has happened.  

Onions, onion powder   

If your dog drinks antifreeze or eats rat poison, immediate treatment is needed. You can induce vomiting by giving 1/2 teaspoonful (small
dog) to 2 teaspoonfuls (adult large dog) of ipecac syrup, but  get him to a vet right away. It is possible to induce vomiting by pouring lots of
very salty water down a dog's throat, but attempts are usually unsuccessful and merely waste time.

Raisins and grapes

Rattlesnake
bites are rarely fatal to large dogs, but little dogs get a lot more venom in proportion to their size, and may die.
However immediate veterinarian care is recommended to assess the extent of the poisoning, and recommended treatment plan.

Salt

Chewing on the toads causes alarming symptoms of salivation and disorientation, but seldom anything worse. Toad-chewing in Florida
and some other places can be much more serious.  

Yeast dough


Do not
try to induce vomiting if petroleum distillates, caustics, or acids have been ingested, if a pet is having seizures, and/or is not fully
conscious.
