Onions are a member of the Allium family, which also includes garlic, leeks, shallots, and chives. Whether raw or cooked, these vegetables contain compounds known as thiosulphates that can be toxic when ingested by certain animals.

Labrador dogs are among those animals that are sensitive to thiosulphates, which can cause anemia in Labrador dogs if they consume enough of it.

However, it is important to note that while onions are not toxic in low doses, they still should not be fed to your Labrador dog regularly.

This type of anemia is termed “hemolytic anemia” because it destroys red blood cells faster than they can be replaced by the body.

Symptoms of onion poisoning include vomiting, diarrhea, lethargy, pale gums, increased heart rate and difficulty breathing. In severe cases, it can lead to organ failure and death if left untreated.

If there is suspicion that your pet has been poisoned with onions then blood tests will be conducted in order to measure for anemia as well as evaluate liver function since both organs may be affected by onion toxicity.

Treatment may involve intravenous fluids along with oxygen therapy depending on how severe the anemia has become due to the toxicity of onions or garlic.
