It’s concerning when your dog eats something potentially harmful like onions. Onions can be toxic to dogs, and even small amounts can be dangerous depending on a dog's size and health.
- Onions contain compounds that can damage red blood cells in dogs.
- Watch for symptoms such as weakness, vomiting, or breathing difficulties.
- If you're in doubt, immediate vet consultation is advised.
Onions contain thiosulfate, which dogs cannot digest well. Ingesting onions can lead to hemolytic anemia, a condition where your dog's red blood cells break down. Given that your dog ate approximately an ounce, it is important to watch for any unusual symptoms. Symptoms to watch for include lethargy, reduced appetite, vomiting, or changes in breathing. If any of these occur, please take your dog to the vet as soon as possible.
