My dog just ate about 5 oz of onions and he’s only 23 pounds—should I rush to the vet?

Earlier today, my dog managed to snatch about 5 ounces of cooked onions from the counter. He’s a small guy, weighing only 23 pounds, and I’m quite anxious because I’ve heard onions can be harmful to dogs. Should I be rushing to the vet right away, or is it likely to be okay if I keep a close eye on him at home?

Answer

It sounds like your dog has ingested a significant amount of cooked onions, which can indeed be harmful. Considering his small size, I would recommend erring on the side of caution and contacting a veterinarian promptly.

  • Onions can be toxic to dogs, potentially causing damage to red blood cells.
  • Small dogs like yours are more susceptible to adverse effects from onion consumption.
  • Monitoring for symptoms such as weakness or vomiting is important, but proactive veterinary advice is best.

Onions contain compounds that are toxic to dogs and can cause a condition called hemolytic anemia, where red blood cells are destroyed faster than they are made. Given your dog's weight and the amount consumed, it would be wise to seek veterinary guidance without delay. Watch for symptoms such as vomiting, lethargy, or a discolored gum line, and don't hesitate to reach out for professional help.

If this is an emergency, please seek immediate veterinary care.
