Can Dogs Eat Onions? (November 2018)

Either you like onions or you’re don’t – there’s really no in between.

With that said, can dogs eat onions?

Are onions safe for dogs to eat?

Let’s take a look at the big answer to our questions.

Can Dogs Eat Onions?

No, dogs cannot have onions. Under no circumstance should your dog ever have access to onion, even in small amounts.

The Risks of Feeding Your Dog Onion

Onions contain thiosulphate, which is toxic to not only dogs, but cats, as well.

When a dog ingests onion, something extremely scary happens inside their body – their blood cells burst.

Hemolytic anemia is characterized by the destruction of the body’s red blood cells, which occurs when a dog eats onion.

ALL types of onions are toxic, whether they are cooked or are raw.

Dogs have experienced onion toxicity even if they’ve only managed to ingest small amounts. Up to 0.5% of your dog’s body weight is considered to be too much.

The next time you think about wanting to give your pup a bite of what you’re eating, think about what’s in it and whether or not it’s a possibility onion could be one of the ingredients.

If you aren’t sure, don’t give your dog any. Better safe than sorry.

Symptoms of onion poisoning include:

  • Breathlessness
  • Diarrhea
  • Vomiting
  • Lethargy
  • Loss of appetite
  • Loss of interest in food

Dogs experiencing onion toxicity can have symptoms for a couple of days.

However, that doesn’t mean you should just let it run its course. Take your dog to the vet as soon as you possibly can.

This is especially important if your dog is a senior pup. Older dogs can die a lot faster than younger dogs can from symptoms such as these.

Either way, onion toxicity equals a trip to the vet.
