These layered wonders are perfect for us humans, but can dogs eat onions? Keep reading to know how onions affect canines and whether you should be feeding them to your dog.

So, Can Dogs Eat Onions?

The short answer is no, dogs can’t and shouldn’t be eating onions. Every single part of the vegetable is toxic to dogs; leaves, flesh, juice, and even powder form should be far from your pooch. This also includes onions in raw and cooked forms.

Why Onions Are Toxic to Dogs

But what makes onions toxic to dogs?

Onions are part of the allium species, which includes garlic, chives, and leeks. They all contain n-propyl disulfide, an oxidant that attaches itself to red blood cells.

Once attached, the body recognizes the blood cells as a foreign body and breaks them down, causing “oxidative damage.” This, in turn, can lead to anemia. This red blood cell breaking process is called hemolysis and can cause hemolytic anemia.

How Much Is Too Much?

If your dog sneaks a small bite of onion, it shouldn’t be much of a concern. However, you should monitor how much onion is getting into your pooch’s system.

Your dog’s size plays a huge role in how easily onion toxins affect them. Smaller dogs like Yorkies are at higher risk versus bigger dogs like Rottweilers or Great Danes. The general toxic dose per kilogram of your dog’s weight is 15-30 grams of onion.

Keep an eye on the ingredients list of your favorite packaged soups and snacks, as they may contain onion powder or onion flavorings that may harm your pup.

Symptoms of Onion Toxicity

Your dog got to an onion, now what? You should start monitoring your dog for the following symptoms:

  • Decreased appetite
  • Vomiting
  • Panting
  • Pale gums
  • Lethargy and weakness
  • Fainting
  • Elevated heart rate
  • Dark or reddish urine

Onion toxicity can be potentially lethal, so once you notice any of these symptoms on your dog, it’s time to rush to the veterinarian.

They will be able to diagnose whether it was caused by onion toxicity or if there’s another underlying condition. The vet may either induce vomiting or administer charcoal tablets.

Wrap Up

Can dogs eat onions? The answer is no. If your pooch sneakily chomps a small bite, they won’t be at risk. The risk of onion toxicity will get higher when your dog consumes more than a small bite. This includes raw, fried, and processed onions.

You should also avoid sharing any snacks that contain onion powder since it has the same risk factor as a regular onion.

So no matter how much your furry friend begs, you should never give them onions or any onion-flavored food.
