DOGS MUSTN’T EAT ONION!

The first question that comes is Why?

Except for the bad breath that your dog can get by eating onion, it can also get serious health problems that sometimes may end up fatal.

Do I have your attention now?

Onion is a vegetable from the Allium family as veggies like garlic, scallion, leek, and chive. All these veggies are toxic to dogs.

You may be like they aren’t toxic to us but how they can be to our pets. It’s easy. The digestive system of dogs is much more different and delicate than humans.

Dogs shouldn’t consume red, green, yellow, white, or sweet onion. Likewise with all parts of onion – leaves, flesh, skin, and juice.

Why Onion is Toxic to Dogs?

Well, onions contain a principal toxin, known as N-propyl disulfide, that damages the red blood cells of your puppy, and by damaged red blood cells, it’s easy for dogs to get anemia. When red blood cells are damaged they are not able to carry oxygen anymore.

The step after the damage is destroying red blood cells, which causes hemolytic anemia. This condition is life-threatening and it’s described as a process where the immune system of your dog isn’t fighting infections but is fighting the red blood cells.

The poisoning dose of onion is reported to be for dogs that consume more than 0.5% of their body weight in grams of onions.

Signs of onion poisoning can show up after a day or a few days after consuming onion. Another case is when N-propyl disulfide builds up in the blood slowly over time and that happens if the dog consumes a little bit of onion but regularly. And out of a sudden for you, your dog will not feel good because of this buildup.

Signs of Onion Poisoning

Here is a list of symptoms your dog may experience during onion poisoning:

  • diarrhea
  • vomiting
  • abdominal pain
  • loss of appetite
  • pale gums
  • increased heart rate
  • weakness
  • lethargy
  • increased respiratory rate
  • change in color of urine

These signs can show up a day or more after the onion intake. That’s why it’s important to pay attention to your dog and get to the veterinarian clinic immediately.

How to Treat Onion Toxicity?

Your vet can diagnose the condition of your dog after some blood work and the symptoms the dog is showing. Onion toxicity is diagnosed if the vet finds hemolytic anemia or a buildup of Heinz’s bodies on a blood smear.

The first thing your vet may do is induce vomiting but depends only on how recent was the onion consumption. In many cases, the first thing vets offer is supportive care while that time your dog is able to produce enough amount of healthy red blood cells to replace the damaged red blood cells.
