Can dogs eat onion?

Answered by Antonio Sutton

Dogs should not eat onions or any part of the onion plant. Onions contain a substance called thiosulphate, which is toxic to dogs. This substance can cause a condition called hemolytic anemia in dogs, where the red blood cells are destroyed faster than the body can replace them.

The toxicity of onions applies to all forms, whether they are raw, cooked, fried, or powdered. Even small amounts of onion can be harmful to dogs. It’s important to note that other members of the allium family, such as garlic, shallots, leeks, and chives, also contain thiosulphate and can have the same toxic effects on dogs.

The symptoms of onion toxicity in dogs can vary depending on the amount consumed and the size of the dog. Some common signs include weakness, lethargy, pale gums, rapid breathing, vomiting, diarrhea, loss of appetite, and dark urine. In severe cases, dogs may experience collapse, jaundice, and even death.

It’s crucial to be cautious when cooking for or feeding your dog any food that may contain onions or other alliums. This includes dishes like onion soup, stir-fries with garlic and onions, or even certain seasonings and sauces that may contain onion powder.

If you suspect that your dog has ingested onions or any form of alliums, it is important to seek veterinary attention immediately. The veterinarian may induce vomiting or administer activated charcoal to prevent further absorption of the toxic substances. Supportive care, such as intravenous fluids and blood transfusions, may also be necessary in severe cases.

It’s important to note that some dog breeds, such as Japanese breeds like Shiba Inus and Akitas, have a higher sensitivity to onion toxicity. Even small amounts of onions can be extremely dangerous for these breeds, so extra caution should be taken.

Onions and alliums are toxic to dogs and should be avoided in their diet. It’s always best to err on the side of caution and keep these potentially harmful foods away from your furry friends. Remember, their health and well-being are in our hands, and responsible pet ownership means being aware of what is safe for them to eat.
