No, dogs should not be allowed to eat onions.

Some of the foods which we enjoy to eat can also be shared with our four-legged best friend, but onions are certainly not one of them.

Onions contains N-propyl disulfide, which causes red blood cells to break down which then leads to anemia in dogs. The N-propyl disulfide will attach itself to oxygen molecules within your dog’s blood cells, this then causes oxidative damage. Preventing blood carrying oxygen around the body properly.

Not only this, but it also causes a dog’s immune system to attack its own red blood cells, which is called hemolsis.

Onions are part of a family of root vegetables called Allium. These include the onion, garlic, leek, shallot, chive and more. All of these vegetables are toxic to dogs and should be avoided!

How much Onion does it take to be Toxic to a Dog?

Not a lot, toxicity will occur if a dog consumes more than 0.5 percent of its total body weight in onion, in a short space of time.

Therefore, a small dog would only need to consume a very small amount of onion or another Allium food to become really ill. And it wouldn’t take too much to cause health problems to a big dog breed either.   

Even very small amounts of onion over time will build up in a dog’s body and can cause toxicity.


My Dog ate Onion!

There is a good chance if your dog ate a very small amount of onion, they wouldn’t become sick, particularly if it is a large dog breed. Dogs don’t generally like the taste of onion, so there is a good chance he/she wouldn’t eat enough to cause a major problem.

However, if your dog has eaten any amount of onion, I would advise seeking advice from your veterinarian straight away.

Never give human food to your puppy or dog unless you have researched it thoroughly and confirmed with your vet, that it is safe for your dog.

Keep onions, garlic, and other allium vegetables well out of reach of dogs.
