Onions belong to the Liliaceae family and the Allium genus. Dogs and cats can easily cause poisoning after eating them. The main symptoms are red or reddish-brown urine. The disease is more common in dogs and less common in cats.

Cause of disease: Onions are rich in nutrients, have a special pungent smell, are rich in Vc, are beneficial and harmless to the human body, and are very popular among people. However, they can easily cause poisoning in dogs after eating them. After a dog eats onions, it will not only stimulate the dog's gastrointestinal tract and cause an inflammatory reaction, but also the spicy volatile oils, volatile toxic components N-propyl disulfide or propylene sulfide in the onions are not easy to be cooked, Destroyed by heating such as drying, the older onions or green onions have more of them. If G6PD activity is weakened, oxidants can denature and coagulate hemoglobin, causing rapid lysis of red blood cells and the formation of Heinz bodies. The reticuloendothelial system engulfs a large number of red blood cells containing Heinz's bodies, causing acute hemolytic anemia. Old red blood cells are more susceptible to oxidative degeneration and dissolution than young red blood cells after poisoning with G6PD. Red blood cells of weak animals are also prone to dissolution. After the red blood cells are lysed, hemoglobin is excreted in the urine, that is, the sick dog may have clinical symptoms such as hemoglobinuria, vomiting, diarrhea, depression, and heart palpitations.

Clinical symptoms: Dogs and cats characteristically discharge red or reddish-brown urine 1-2 days after eating onions. The symptoms of mild poisoning are not obvious, and sometimes they are depressed, poor in energy, poor in appetite, and produce light red urine. Dogs with severe poisoning will show depression, poor appetite or loss of appetite, followed by vomiting, diarrhea and other symptoms, unsteady walking, preferring to lie down, yellowing of the conjunctiva or oral mucosa, rapid heartbeat, panting, weakness, and excretion of dark red fluids. urine, the condition gradually worsens, the body temperature becomes normal or drops, and severe poisoning can lead to death.

Diagnosis is based on the history of disease, clinical manifestations of sick dogs and laboratory tests. Laboratory tests: Blood tests: Blood gradually becomes thinner with the degree of poisoning, the number of red blood cells, hematocrit and hemoglobin decreases, the number of white blood cells increases, and there are spots in or on the edges of red blood cells. Heinz corpuscles. Urine examination showed that the color of the urine was red or reddish-brown, the specific gravity was increased, urine occult blood, protein and urine hemoglobin tests were positive, and there were few or no red blood cells in the urine sediment. It can be diagnosed as onion poisoning.

Treatment Measures Once a dog is found to be poisoned by onion food, the first step should be to stop feeding onions or green onions immediately. The antioxidant VE can be used to protect hemoglobin and prevent the formation of Heinz's bodies; support therapy, fluid replenishment, and nutrition can be taken; an appropriate amount of diuretics can be given to promote the excretion of denatured hemoglobin in the body, and a certain amount of antibiotics can be used to prevent the body's resistance Secondary infection may occur due to decreased blood flow: For severe anemia, blood-replenishing drugs can be used. Of course, intravenous blood transfusion is preferred to obtain better curative effects.

Treatment plan: ① Dexamethasone, Vc, 50% glucose aqueous solution, 5% sugar saline, mixed intravenous infusion. Intravenous blood transfusion 10-20mg/kg body weight. ②2 Furosemide injection, intramuscular injection. ③VB12 injection, intramuscular injection. (Suggestions only, specific operations need to be carried out according to the localMake judgments based on the current situation and follow the attending doctor’s plan)

Summary and experience: Do not feed onions or green onions to dogs. Once a dog or cat is found to have eaten a large amount of onions by mistake, they should immediately take measures such as easing diarrhea and inducing vomiting, and go to a nearby animal hospital as soon as possible.
