Dogs or Canis Familiaris are most commonly referred to as “Man’s best friend,” a loyal companion and probably the first species to have been tamed by humans. Today more and more would be seen having at least one dog in their home.

They not only act as guards, today’s generation most commonly treat them as a part of the family and are therefore strict on what kind of foods their pet eats. However, what are foods that are safe for dogs and what are not?

Components Found in Onions

Today you will be looking into whether onions are safe or not for your pet dogs but before anything else, you must know first what the components of onion are.

Nutrients

89% water, 9% carbohydrates which includes roughly 4% sugar and 2% dietary fiber, and a percent of protein. Onions lack the essential nutrients like amino acids which are most commonly required for a normal physiological function.

Dogs however require at least Vitamins A, D, E, K, C, and B while the onions have Vitamin C and B1-B9 in it.

Minerals

Aside from the 166 kJ or 40 kcal of energy that the onion has, it also has calcium, iron, magnesium, manganese, phosphorus, potassium, and zinc which would prove useful to your dog’s health.

Calcium is a necessary mineral for your dog especially when it is still in its growth and suckling stages. While Phosphorus and Potassium help with its bone structure and for the energy it needs while growing up.

There is however a component you need to worry about. Sure, the onion has a lot of minerals and does contain Vitamin C in it which is healthy for humans but maybe not for canines.

Onions also contain a principle known as N-propyl disulfide, an oxidant known to be harmful to your dogs and cats.

Can Dogs Eat Raw Onions

The answer is NO, the oxidative damage that onions bring to your dogs can lead to anemia. The N-propyl disulfide attaches itself to the oxygen molecules in your dog’s red blood cells and is destroyed during the process known as hemolysis, this phenomenon is most commonly referred to as hemolytic anemia.

What part of the onion is toxic for your dog? All parts including the processed powders produced by the onion’s leaves and also its juices.

Can Dogs Eat Cooked Onions

Cooked onions do not change the fact that the oxidants present in the raw onion are still there and therefore will still be harmful to your dogs. Can dogs eat green or can dogs eat red onions?

The answer will still be the same, these toxins are present on all vegetables in the allium genus family. Scallions, Shallots, Garlic, Leeks, and even Chives. Each and one of these vegetables are harmful to your pet’s health.
