Thank you,

Now onions can be a problem for dogs. As you are seeing, they can cause nausea and GI upset. That said, in large doses it can also damage red blood cells to cause anemia. That said, given Ivan's weight, this is a thankfully a low dose ingestion.

Therefore, we have a few options here. Since he just had this so recently, we can err on the side of caution and induce vomiting now. To induce vomiting at home, you can administer 3% hydrogen peroxide orally at a dose of 1ml per pound. (2 teaspoons per 10 pounds of body weight). You can give it via dropper, syringe, turkey baster – we just want to get it in. After giving this orally, move the abdomen around or get your wee one walking about to get things mixing. This should usually lead to vomiting. If it is unsuccessful after 10 minutes then it can be repeated twice more. And if we still have no vomiting, then you'd need to consider seeing your local vet (or ER vet) so that apomorphine (a very strong injectable emetic) can be administered just get this out of the stomach and avoid any adverse issues.

Otherwise, we can choose to monitor and just address any potential GI upset here for the next 24-48 hours. To do so, you can consider offering a light diet option for a few days. Examples of an easily digestible diet include cooked white rice with boiled chicken, boiled white fish, scrambled egg, or meat baby food (as long as its free from garlic or onion powder). Ideally, we want to offer this as small frequent meals to keep the stomach settled. Further to this, for his nausea we can also treat with an antacid. There are a number of antacids that are available over the counter and pet friendly. Ones we can use here include Pepcid (More Info/Dose @ or Zantac (More Info/Dose @ Whichever you use, we'd give this 20 minutes before food to allow absorption and of course double check with your vet before use if your wee one has any known health issues or is on any medications you haven't mentioned. And as this is a low dose toxicity, we'd hope to get him settled with that if you chose not to induce vomiting.

Kind regards,

Dr. B.
