What to do if the dog ate rat poison

отравление собаки крысиным ядом Poisoning with rat poison in dogs is rare, as bait for rodents is not very attractive in terms of carnivores. Also for the manifestation of the action of poison, it is required to take a sufficiently large dose. The number of patients who applied for veterinary care in case of poisoning of dogs with baits for rodents is less than 0.1% of cases.

The risk of eating a dog with poisoned baits increases if they are made on the basis of meat components. In addition, the animal can be poisoned if it eats several carcasses of a rodent killed from poison. Rare, but serious cases are intoxication rodenticides (poisons for rodents) acute action.

  • zinc phosphide.

When the dog is poisoned with rat poison, the signs will depend on the group to which the rodenticide belongs.

Why dangerous rat poisons for dogs

The action of rat poison on dogs is distinguished by the types of toxin.

  1. Anticoagulants of the first generation (warfarin, ethylphenacin, isopropylphenacin, triphenacin) - the most common active ingredient in rodents baits. The mechanism of action is based on a violation of the synthesis of vitamin K and the loss of the ability of the blood to coagulate. The poisons of this group are relatively quickly eliminated from the body. Dogs show a specific sensitivity to warfarin, the lethal dose for them is 6 mg / kg body weight. For ethylphenacin this dose is 7000-70000 mg / kg of weight.
  2. Anticoagulants of the second generation (bromadiolon, brodifacum, flocumafen). The mechanism of action is the same as in the first group of rodenticides, but these poisons are able to accumulate in the body, the period of excretion is longer, and therefore they are stronger. The lethal dose of brodifacum for dogs is 3.5 mg / kg body weight.
  3. чем опасен крысиный яд The rat. It is used rarely because of high toxicity. Causes pulmonary edema, convulsions and vascular reactions. The lethal dose for dogs is 60-150 mg / kg of body weight. It is used in the form of 10% gel.
  4. Zinc phosphide is very toxic, it is used only under the control of specialists in deratization (destruction of rodents). When poison enters the stomach, hydrogen phosphorous is released, which destroys the gastric mucosa and acts on the nervous system.

If the dog ate a rat poison with anticoagulants, then the toxin effect will manifest not immediately, but in 3-5 days. This is due to the presence of vitamin K in the body.

Symptoms of poisoning with rat dog poison

Consider the signs of poisoning with rat poison in dogs, which includes anticoagulants (zookoumarins, coumarins):

  • weakness;
  • dyspnea;
  • pallor of the mucous membranes;
  • bleeding from the nose, gums;
  • lack of appetite.

In severe cases, bleeding from the rectum, blood in the urine, subcutaneous hemorrhage, abdominal pain, lameness, coughing up with blood. The animal dies from numerous hemorrhages.

With timely provision of veterinary care, the prognosis is favorable - more than 85% of dogs recover. However, the owners should be aware that with a repeated poisoning with rat poison, the chances of recovery are less, since the animal has an increased sensitivity to it.

Krysid and zinc phosphide are practically not used at present. When poisoning with rat poison the symptoms of zinc phosphide are:

  • vomiting, sometimes with an admixture of blood;
  • симптомы отравления крысиным ядом diarrhea;
  • thirst;
  • weakness;
  • labored breathing;
  • dilated pupils;
  • anxiety;
  • convulsions;
  • loss of consciousness.

  • rinse the stomach with a slightly pink solution of potassium permanganate;
  • give any adsorbent (activated carbon suspension, "Polysorb MP", "Enterosorb", "Polyphepan");
  • give the dog a salt laxative (magnesium sulfate);
  • water the dog with slimy decoctions, best of all with flaxseed, but you can also rice or Herculean.

What can not be done? Do not induce vomiting, if after eating the bait more than 4-6 hours have passed - from the stomach everything has already passed into the intestines. Also, do not induce vomiting, if the dog has signs of impairment of the nervous system: convulsions, loss of consciousness, paralysis.

Do not give the animal milk, eggs, vegetable oil, castor oil. When zinc phosphide is poisoned, it only speeds up the absorption of poison into the blood.


In case of poisoning with anticoagulants, the antidote is vitamin K1 - phytomenadione. It is administered subcutaneously in a dose of 2.5-5 mg per kg of dog weight. If it is known that the animal has eaten a bait with a rodenticide of the first generation, then the dose will be less - 0.25-2.5 mg per kg.

When a rat is poisoned with a specific antidote there. In the stomach, the poison is tied with a 1% solution of tannin.

When eating lures with zinc phosphide inside give a 0.5% solution of copper sulfate to the appointment of a veterinarian or 2% solution of baking soda.
