Answer

It's understandable to be worried if your dog ate onions, as they can be harmful to dogs. However, whether your dog becomes sick depends on the amount consumed and their size.

  • Onions can cause toxicity in dogs even in small amounts.
  • Watch for symptoms like vomiting or lethargy.
  • Immediate veterinary advice is recommended if your dog shows any concerning signs.

Onions can lead to a condition called haemolytic anaemia in dogs, which affects their red blood cells. Symptoms might include weakness, decreased appetite, or a change in their usual behavior. Since the severity can vary, it’s best to consult a vet, especially if you notice any unusual symptoms.
