Eating a small amount of spring onion is unlikely to cause harm to your dog, but onions are part of a group of plants that are toxic to dogs. It’s important to be cautious and monitor your dog for any signs of illness.
- Spring onions belong to the allium family, which includes onions, garlic, chives, and leeks—all toxic to dogs.
- Consuming large amounts of allium can damage red blood cells and cause hemolytic anemia in dogs.
- Immediate symptoms of onion toxicity might include vomiting, diarrhea, lethargy, or lack of appetite.
- If your dog ate only a small piece, he is likely to be okay but should be monitored for any symptoms.
The reason spring onions can be dangerous is that they contain compounds that can damage red blood cells and lead to a condition called hemolytic anemia. Keep an eye on your dog for the next few days, and if you notice any worrying symptoms such as change in energy levels, breathing difficulties or color changes in the gums, consider reaching out to a vet.
If you’re unsure or your pet’s symptoms are getting worse, book a consultation with a licensed vet at Dial A Vet for just $49 AUD.
