What Are Green Onions?

Green onions are a part of the allium family. Unlike other allium family vegetables, green onions have a mild smell. It is a staple ingredient in most of the cuisines found in the world.  

What is an allium?

Scallion’s etymology goes thus: it is considered that an ancient Greek writer Theophrastus described the tubular bulb as Askolonion. However, many believe that the term Askolonion has developed from the ancient Canaan city Ashkelon.

Are Green Onions Safe For Dogs?

No, green onions are not safe for dogs. The entire vegetable is toxic due to the compound present in them. The n-propyl disulfide is a chemical compound that dogs cannot tolerate. Therefore, all the vegetables in the allium family are toxic to dogs. 

Why Is Green Onion Bad For Dogs?

Green onions or scallions have n-propyl disulfide, which is dangerous for dogs. Dogs do not have enzymes to break the compound and digest it. N-propyl disulfide also binds with the red blood cells, specifically the hemoglobin, which carries oxygen to the entire body. As a result, it affects the red blood cells and cuts down the oxygen supply in the body. This condition is referred to as oxidative damage. 

The consequences of consuming green onions are:

  • Hemolytic anemia
  • Heinz body anemia
  • Methemoglobinemia
  • Vomiting
  • Weakness
  • Blood in urine
  • Loss of appetite
  • Lethargy
  • Decreased stamina
  • Accelerated heart rate
  • Diarrhea
  • Abdominal issues
  • Pale or bluish gums
  • Yellow eyes
  • Loss of coordination
  • Fainting
  • Exercise intolerance
  • Hyper-salivation
  • Tremors
  • Seizures
  • Kidney failure
  • Coma
  • Death

In addition, green onions contain thiosulphate, toxic for dogs. It becomes toxic for dogs as they don’t have enzymes involved in breaking this compound, making it difficult to digest. 

How Much Green Onions To Feed My Dog?

You should strictly never provide your dog with green onions. The toxicity happens very fast, and you could lose your dog forever. In addition, vegetables from the allium family can be very dangerous to your dog. All the parts of the specific vegetable can be deadly if consumed. 

What If My Dog Ate Green Onions?

If your dog ate green onions accidentally from your table scraps or the countertop, it would be best if you rushed to the vet at the earliest. The symptoms might not show immediately, but they will occur within 24 hours of ingestion. However, the signs which will surface are:

  • Lethargy
  • Vomiting
  • Diarrhea
  • Blood in urine

  • Decreased stamina
  • Pale gums
  • Loss of appetite

You can do the water therapy at home and then visit the vet. Provide your dog with enough water to ease his stomach. However, this is not going to solve the issue. After taking him to the vet, (s)he will:

  • Use IV fluids
  • Flush the stomach to remove undigested pieces and toxins.
  • Supply extra oxygen
  • Arrange blood transfusion

After the diagnosis and the treatment, the dog must stay in the clinic under the vet’s observation. Few dogs will be okay and step back home, and few will have to wait for more days until the issue is nearly over.
