Can Dogs Eat Chicken Broth with Onions? (Read This First!)

Chicken broth is one of the safest liquid food that a dog can consume without having any serious health issues. However, many Chicken broths, especially the store-bought ones can contain ingredients from the allium family like onions.

If you don’t know whether chicken broths containing onions are safe for your dog’s health or not, you must be concerned enough to know can dogs eat chicken broth with onions or not.

Therefore, to end the concern regarding such an important issue, let’s read further to learn the answers.

Can Dogs Eat Chicken Broth With Onions?

Dogs can’t eat chicken broth with onions because onions have an oxidant named N-propyl disulfide. If dogs eat onions, this oxidant pact with oxygen molecules and damages their red blood cells. Thence, oxygen can’t be transported throughout dogs’ bodies and pushes them to a fatal health condition.

For the safety of your beloved four-legged furry friend, here is an overview of the digestibility of chicken broth with onion powder and onion juice.

Chicken Broth With Onion Powder:

Dogs can’t and shouldn’t ever eat chicken broth with onion powder.

As it’s known that onion contains N-propyl disulfide oxidant so even if it’s powdered onion, it’s just as poisonous and harmful to dog’s health as fresh and raw onion flesh.

And the toxicity is so high that even if a dog consumes onion powder as tiny amount as 15-30 gm/kg of a dog’s total weight or around merely 0.5% of a dog’s body weight, it will affect the dog’s health severely.

Chicken Broth With Onion Juice:

Every form of onion regardless of onion powder or onion juice is considered extremely poisonous for a dog’s overall health as onion juice has N-propyl disulfide oxidant too.

This already is indicating that chicken broth with onion juice is equally toxic and dogs can’t eat chicken broth with onion juice.

If a dog continues to eat chicken broth with onion juice, initially the dog will suffer from gastrointestinal irritation. And then it will turn into anemia that can direct to organ failure.

Will A Small Amount Of Onion In Chicken Broth Hurt A Dog?

If the dog has been eating a small amount of onion regardless of powder, flesh, juice, or any other form of onion each day for several months, it surely will hurt the dog severely.

However, onions are awfully toxic, so even if the amount of consumed onion surpasses 0.5% of a dog’s weight each time, it is likely to get affected by onion’s toxicity gradually and seriously.

What Happens When Dogs Eat Chicken Broth With Onion?

As a dog owner, you must be concerned to know exactly what can happen to a dog if it eats chicken broth with onion. Therefore, here the most potential side effects/health issues that a dog can suffer from are explained precisely.

Hemolytic Anemia:

Hemolytic anemia is a fatal health condition that attacks dogs due to oxidative damage. And oxidative damage occurs because of the N-propyl disulfide oxidant contained by onions which is basically a sulfur compound and it’s severely hazardous for dogs.

When a dog eats onion through chicken broths, the N-propyl disulfide creates a bond with oxygen molecules of its body’s red blood cells which will cause oxidative damage.

Therefore, oxidative damage will keep damaging and obstructing the dog’s red blood cells from transporting oxygen through its body. And soon it will direct to fatal hemolytic anemia.

Kidney Failure:

Kidney failure is another bad health condition that onions in chicken brother can cause to a dog.

If a dog keeps consuming chicken broth with onion or if its hemolytic anemia is not treated on time, it can suffer from kidney failure. Because oxidative damage makes the membranes of red blood cells fragile and destroys them.

Thereby, kidneys and other significant organs don’t get oxygen, and kidney failure occurs.

The worst:

The harsh reality is onion toxicity can lead a dog to the end of it’s life as well. Because if a dog consumes 100 gm of onion (in any form through the chicken broth) per 20 kg of its weight, it will suffer from immediate toxic effects of onions that can lead to loss of life.

Because just 100 gm onion (it’s about a medium-sized onion) can cause immediate anemia in a 45 pounds dog. Later this anemia will lead to organ failure and the worst.
