If your dog ingests a small piece of red onion, it’s wise to monitor them since onions can be toxic to dogs. However, small amounts are often not immediately harmful, but you should watch for symptoms of onion toxicity.
- Vomiting or diarrhea
- Weakness or lethargy
- Panting or elevated heart rate
- Red or brown urine
- Decreased appetite
Onions contain compounds that are harmful to dogs, potentially causing hemolytic anemia, where red blood cells are destroyed. Even a small amount can be a concern, particularly in small breeds or if ingested in combination with other toxic foods. Monitoring is crucial; if symptoms appear, contact your vet promptly.
