Is it harmful if my dog ate a little cooked onion from dinner, do I need to do anything fast?

While cleaning up after dinner, I noticed my dog had snatched up a small piece of cooked onion that fell to the floor. I've heard that onions can be harmful to dogs, even in small amounts. Do I need to do anything immediately to ensure my dog's safety, or is there a chance that such a small amount isn't too concerning?

Answer

Onions are toxic to dogs, and even small amounts can pose a risk. It's important to monitor your dog for any signs of distress or illness.

  • Onions contain compounds harmful to dogs.
  • Look for symptoms like vomiting or lethargy.
  • Contact a vet if you're unsure or symptoms appear.

Even in small amounts, onions can be harmful because they contain thiosulfate, which dogs cannot digest. Watch your dog closely for symptoms such as vomiting, diarrhea, weakness, or lethargy over the next 24 hours. If your dog shows any of these signs, it would be wise to consult a vet.
