Dogs must never eat onions. Onions, onions or processed foods containing onions can cause onions poisoning, which can endanger life in serious cases.
The onions are toxic to dogs.
Onion components, such as n-propyldisulphides, can damage the red cell of the dog, causing haemoglobin oxidation to form the Heinz small body and causing acute soluble anaemia. Dogs may be poisoned by the lack of enzymes to metabolize such sulphides, even in small quantities.
2. Potential hazards and symptoms
Acute intoxication: 1 - 2 days of insulation, in the form of red urine (light red to coffee colour), vomiting, diarrhoea, depression and, in serious cases, yellow stun, shock and even death.
Chronic intoxication: Long-term microingestion may lead to mild anaemia and bone marrow damage. Zenium
Dose-relation: The dose was about 15 g/kg body weight, and small dogs could be fatal by miseating small amounts. Zenium
3. Effects of onions with small intakes
Onions are also dangerous: heating does not decompose toxic ingredients, and onions or onions are still hazardous.
A small amount of ingested antipolymers: If the dog is of high weight and has little ingestion (e.g., trace onions), the symptoms can be closely observed and more water fed to promote metabolic; however, if the dog or intake is unknown, it needs immediate treatment. It's gone.
