Can Dogs eat Onion (…. No)

Onions should not be given to Dogs as they are toxic dogs. Onions can cause serious complications in dogs. Onions in raw, baked, fried, as well as cooked form should not be given to dogs.

Why is it not safe to give onions to dogs?

Some owners admit that their dog eats green onion from the garden bed with pleasure. At the same time, they did not notice any serious consequences for the condition of the pet. Of course, animals have different organisms, and everyone’s susceptibility to negative factors is also different. Is it worth risking the health of a dog and endangering him?

Important! veterinarians consider all types of onions dangerous for dogs – both green and onions, and lettuce, shallots, leeks.

Onions increase the acidity of gastric juice, but this is not its worst negative property. The hazard is caused by the organic sulfoxides contained in the plant. When onions are chewed, they disintegrate in the animal’s body, and the resulting sulfur formation causes the destruction of red blood cells.

Anemia can develop in literally a few days. The daily use of onions and garlic in any form by a dog can cause dangerous consequences. The rate of development of the disease depends on the state of health of the animal, as well as on the breed – for large dogs the toxic dose is higher than for small ones.

Symptoms of hemolytic anemia:

  • weakness;
  • depressed state;
  • heart palpitations;
  • refusal to eat;
  • vomiting;
  • diarrhea;
  • reddish or dark urine;
  • pale or blue gums.

Onions contain thiosulfate. The dog’s body lacks enzymes to digest it. This substance is toxic to animals. The amount of onion that threatens the life of an animal is 15-30 g per 1 kg of the animal’s body weight, and negative manifestations can be noticeable even with a small amount of food eaten – 5 g of onion may be sufficient.

What are the sings and symptoms of onion poisoning in Dogs:

The main danger of onion poisoning is that its symptoms do not appear immediately, but as toxins accumulate in the body. The dog can chew onions in the garden or pull off the head from the table (purple onions may seem like a treat to the pet – it is not so hot, it has a pleasant sweetish taste), and after 3-5 days it will suddenly feel bad. The owner may not associate the symptoms of the disease with what the dog ate or not know about it at all, and the dog will have:

  • loss of appetite;
  • vomiting;
  • diarrhea;
  • stomach ache;
  • pallor of the mucous membranes;
  • dermatitis;
  • suffocation.

With severe intoxication, the veterinarian can diagnose liver damage. In dogs of large breeds, lethal outcome may not happen, their body can cope with the negative effect of the product, but serious diseases of the internal organs against the background of poisoning are not excluded.


There is also the opposite point of view: some experts argue that onions and garlic increase immunity, so it may even be beneficial for dogs. In addition, they contain natural phytoncides, due to which these products have a destructive effect on bacteria, viruses, and intestinal parasites. However, this point of view has no scientific justification, and statistics indicate that cases of onion poisoning are not so rare.

What to do if the dog has onion poisoning:

There is no antidote, if the owner immediately pays attention to the first signs of poisoning, or even better – notices that the dog is eating onions, it is necessary to contact the veterinary clinic as soon as possible. The very first veterinary aid will be gastric lavage and the use of enterosorbents, which will help to quickly bind and remove toxins from the body before they enter the bloodstream.

The veterinarian will most likely take a blood test to help diagnose hemolytic anemia. If there are signs of an allergic reaction, a specialist will prescribe symptomatic treatment. In case of serious damage to the body, blood transfusion, special drugs to restore liver function may be required. The doctor will prescribe a special diet and will monitor the condition of the animal for a long time.


Dogs should not be given onions, it is contraindicated both fresh and boiled, baked, fried. It negatively affects not only the digestive and cardiovascular, but also the pet’s nervous system, it can provoke an increase in blood pressure, breathing problems.
