The second step is to delay absorption of the poison from the dog's intestinal tract by coating it with a substance that binds it. This is followed by a laxative to speed elimination.
*************************************************
How to Delay or Prevent Absorption
1.Mix activated charcoal (one tablet to 10-cc water). Give one teaspoonful per two pounds body weight and follow with a pint of water. Depending upon the dog's condition, this may need to be given by stomach tube. Veterinary assistance usually is required.

2. Thirty minutes later, give sodium sulphate (Glauber's salt), one teaspoonful per ten pounds body weight, or Milk of Magnesia, one teaspoonful per five pounds body weight.

Note:If these agents are not available, coat the bowel with milk, egg whites or vegetable oil and give a warm water enema.

If your dog has a poisonous substance on the skin or coat, wash it well with soap and water or give a complete bath in lukewarm (not cold) water, as described in the SKIN chapter. Even if the substance is not irritating to the skin, it should be removed. Otherwise, the dog may lick it off and swallow it. Soak gasoline and oil stains with mineral or vegetable oil. Work in well. Then wash with a mild detergent, such as Ivory soap.

When signs of nervous system involvement begin to show, the dog is in deep trouble. At this point, your main objective is to get your dog to a veterinarian as quickly as possible. Try to bring with you a sample of vomitus, or better yet the poison in its original container. If the dog is convulsing, unconscious or not breathing, see Shock and Artificial Respiration.

The poisons discussed below are included because they are among the most frequently seen by veterinarians.
Strychnine - Strychnine is used as a rat, mouse and mole poison. Signs of poisoning are so typical that the diagnosis can be made almost at once. Onset is sudden (less than two hours). The first signs are agitation, excitability and apprehension. They are followed rather quickly by intensely painful tetanic seizures that last about sixty seconds, during which the dog throws the head back, can't breathe and turns blue. The slightest stimulation, such as tapping the dog or clapping the hands, starts a seizure. This characteristic response is used to make the diagnosis. Other signs associated with nervous system involvement are tremors, champing, drooling, uncoordinated muscle spasms, collapse and paddling of the legs.
Warfarin (Decon, Pindone)

Warfarin is incorporated into grain feeds for use as a rat and mouse poison. It causes death by interfering with the blood clotting mechanism. This leads to spontaneous bleeding. There are no observable signs of warfarin poisoning until the dog begins to pass blood in the stool or urine, bleeds from the nose or develops hemorrhages beneath the gums and skin. The dog may be found dead with no apparent cause. A single dose of warfarin is not as serious as repeated doses.

Treatment: Induce vomiting. Vitamin K (for clotting) is a specific antidote. It is given intramuscularly (or in cases where there are no symptoms it can be given by mouth as a preventative).

Antifreeze (Ethylene Glycol)

Poisoning with antifreeze is not uncommon because ethylene glycol has a sweet taste that appeals to dogs and cats. In dogs, a toxic dose is one half teaspoonful per pound body weight. Signs of toxicity, which appear suddenly, are vomiting, uncoordinated gait (seems "drunk"), weakness, mental depression, coma and death in twelve to thirty-six hours. Convulsions are unusual. Dogs that recover from the acute phase may have damage to the kidneys and go on to kidney failure.

Treatment: Induce vomiting. Coat the bowel to prevent further absorption. Intensive care in an animal hospital may prevent kidney complications.

Organophosphates and Carbamates

These substances are used on dogs to kill fleas and other parasites. The common ones are dichlorvos, ectoral and sevin, but there are others. They also are used in garden sprays and in some dewormers. Improper application of insecticides to the dog can lead to absorption of a toxic dose through the skin. These drugs effect the nervous system primarily. For more information, see SKIN: Insecticides.

Treatment: For topical insecticides, bathe your dog immediately using warm soapy water to remove residual compounds from the coat. Call your veterinarian.

Chlorinated Hydrocarbons

These compounds, like the organophosphates, are incorporated into some insecticide preparations for use on the dog. The common products in veterinary use are chiordane, toxaphene, lindane and methoxychior. The treatment is the same as for organophosphates.

Corrosives (Acid and Alkali)

Corrosives and caustics are found in household cleaners, drain decloggers and commercial solvents. They cause burns of the mouth, esophagus and stomach. Severe cases are associated with acute perforation, or late stricture, of the esophagus and stomach.

Treatment: If acid is ingested, rinse out your dog's mouth. Give an antacid (Milk of Magnesia or Pepto-Bismol) at the rate of one to two teaspoons per five pounds body weight. If an alkali, use vinegar or lemon juice. Vinegar is mixed one part to four parts of water. The amount to give is judged by the size of the dog. Do not induce vomiting; this could result in rupture of the stomach or burns of the esophagus.

Petroleum Products (Gasoline, Kerosene, Turpentine)

These volatile liquids can cause pneumonia if aspirated or inhaled. The signs of toxicity are vomiting, difficulty of breathing, tremors, convulsions and coma. Death is by respiratory failure.

Treatment: Do not induce vomiting. Administer an ounce or two of mineral oil, olive oil or vegetable oil by mouth; then follow it in thirty minutes with Glauber's salt. Be prepared to administer artificial respiration.
