Cyanide poisoning Dogs can stop breathing when they inhale high concentrations of gas or swallow lethal doses of sodium cyanide, resulting in sudden death. In non-sudden death poisoned dogs, early manifestations such as weakness, dizziness, headache, nausea, chest tightness, dyspnea, panic, and impaired consciousness can occur until death is complicated by respiratory failure. In severe poisoning with non-instantaneous death, the clinical manifestations can be divided into prodromal, respiratory distress, spasm and paralysis phases, but the phases are often not easily distinguished due to the rapid progress of the disease. Arsenical poisoning is arsenic poisoning. Because it contains sodium arsenite, calcium arsenate, lead arsenate, etc., dogs are poisoned after accidental ingestion. Acutely poisoned dogs suddenly develop severe abdominal pain, muscle tremors, birth, vomiting, staggering, diarrhea, thirst, paralysis of the hind limbs, swelling of the oral mucosa, gums become dark black, and in severe cases, the oral mucosa is seen to ulcerate and fall off. Individual dogs are excited, twitching, sweating, chilling at the end of the body, and some parts of the muscles are paralyzed. In male dogs, the penis can be seen to come out. Poisoning by accidental ingestion of rodenticides 1. This is a powerful rodenticide, a white, odorless crystalline powder that causes increased permeability of the pulmonary capillaries and a large amount of blood plasma to enter the lung tissue, resulting in pulmonary edema. A few minutes to a few hours after ingestion, the dog vomits, foams at the mouth, followed by diarrhea, coughing, difficulty in breathing, depression, cyanosis of visible mucous membranes, and foamy, bloody mucus coming from the nostrils. Generally, coma and drowsiness appear 10-12 hours after ingestion, and a few die within 2-4 hours after ingestion. 2. Zinc phosphide poisoning. This is a commonly used rodenticide, which is a gray powder. A few days after ingestion, it mixes with water and stomach acid in the stomach, releasing phosphine gas and causing severe gastroenteritis. The affected dog has abdominal pain, does not eat, vomits a lot, is comatose and drowsy, and breathes fast and deeply. Suffocation, diarrhea, blood in feces. Organophosphorus pesticide poisoning
Organophosphorus is widely used in agriculture as insecticide, such as trichlorfon, leuconazole, dichlorvos, etc. Accidental ingestion causes profuse salivation, lacrimation, diarrhea, abdominal pain, urinary incontinence, respiratory distress, coughing, conjunctival cyanosis, muscle twitching, followed by paralysis, narrow pupils and coma in dogs.
