Can Dogs Eat Onions

Can dogs eat onions? No, onions are not good for dogs. They’re one of the most dangerous human foods available to our canines. It was discovered that consuming too much onion might damage a dog’s red blood cells, resulting in a potentially fatal condition known as hemolytic anemia.

Let’s have a look at onion toxicity in dogs, so that you know what to avoid for your pet, what onion poisoning might look like in your dog, and what to do if he or she absorbs the toxic plant.

Why are onions bad for dogs?

Experts don’t know precisely why specific poisonous meals for dogs, such as grapes, are harmful. Onions, on the other hand, have a straightforward explanation.

Onions contain a poisonous chemical called N-propyl disulfide that is harmful to canine health. This sulfur substance is at the heart of why onions are so hazardous for dogs.

The chemical N-propyl disulfide binds to the oxygen molecules in your dog’s red blood cells, causing oxidative damage. This prevents the red blood cells from transporting oxygen effectively. That is bad enough on its own, but it also fools your dog’s body into thinking its own red blood cells are harmful. In this way, your dog’s body assaults the red blood cells, known as hemolysis, in order to defend itself.

When the body is exposed to certain poisons, particularly those that are heat-labile or resistant to heat such as antifreeze and gasoline, blood cells break down too rapidly. The breakdown of blood cells generates a substance called Heinz bodies , which causes anemia in dogs. When your dog’s red blood cells are destroyed faster than they can be produced, he becomes poisoned and even dies without treatment if left uncontrolled.

Dogs should avoid all parts of the onion

The leaves, flesh, skin, and juice of the onion are all harmful. It doesn’t matter whether the onion is cooked or uncooked. The disulfide chemical in an onion is not destroyed by cooking it, so it’s just as dangerous for your four-legged companion.

Can dogs eat broth and onions?

If you’re feeding your dog or offering him some goodies from your plate, avoid sharing any food that has been cooked with onions, even if it’s in a broth. “Although a tiny amount of onion is unlikely to cause issues, it is preferable to avoid all together.” According to Hinder,

broth and onions

If you’re buying a pre-made broth, make sure it doesn’t contain onions. Hinder advises dog owners to avoid using onion powder as an ingredient in prepackaged foods because it is composed of dried and ground onions and can be harmful to their dogs.

Regardless of whether you’re using the juice, flesh, or even leaves, onion ingredients will cause problems for your dog. Don’t give your dog something with onions or onion powder to eat.

What should you do if your dog ate onions?

Keep all onions and any products containing onions away from your dogs, to be safe. But what if you’re cooking and a slice of onion falls on the floor or a friend offers your dog a bite of their lunch, which includes onion? While we don’t want our dogs to eat onions, having a taste of something with onion isn’t likely to harm them. Dr. Werber explains that because dogs dislike the flavor of onions, they would not eat enough to cause an issue.

Dr. Werber advises seeking immediate veterinary care if you believe your dog ate a lot of onions, or if your dog appears to be ill. Your veterinarian will be able to examine your dog and determine whether any treatment is required.

Onion poisoning causes anemia in dogs, which is characterized by low red blood cells. Loss of appetite, sluggishness, and pale gums are all symptoms to look for. The ASPCA’s animal poison control site adds that clinical symptoms include vomiting, breathlessness, and a fast heart rate. Take your dog to the doctor as soon as possible if you detect any of these signs.

The Symptoms of Onion Toxicity in Dogs

If your dog eats a large quantity of onions or other similar items in a short amount of time, toxicity may develop rapidly. However, symptoms are less likely to show up after several days of consumption.

Because of your dog eating little amounts of an allium-family food for a long period, N-propyl disulfide may be absorbed into the blood gradually over time.

How Much Onion Is Too Much for a Dog?

Another cause of onion toxicity in dogs is that it takes only a tiny amount to cause significant health issues. In general, toxicosis occurs when a dog eats more than 0.5 percent of its body weight in onions at once.

To put it another way, even a little amount of onion, garlic, or other allium food can swiftly kill a dog. The smaller the dog is, the more dangerous it is — eating a tiny bit of onion may not harm a 150-pound mastiff but it can cause serious health problems in a 10-pound chihuahua. It’s critical to understand what kinds of human meals your dog can consume safely since there are some that are good for dogs and others that can be harmful to his/her health.
