Onions & Dogs

Unfortunately, onions are toxic to dogs. All parts of the plant are toxic. In addition, dried onions are also toxic. What’s more, these vegetables are toxic whether a dog eats them alone or the onions are included in a dish.

These veggies contain a substance called N-propyl disulfide. When the dog ingests onion, this substance binds to oxygen molecules in the dog’s red blood cells. The body then sees these cells as foreign invaders, and the immune system attacks them.

When this happens, the dog’s blood is not able to carry oxygen to organs and tissues. Lack of oxygen may cause the dog to become weak, pant, and more. Depending on the amount of onion eaten, these symptoms can even lead to death.

Symptoms of Onion Toxicity in Dogs

You may notice these symptoms if your dog eats some onion:

• Vomiting
• Anemia
• Blood in the urine (urine has a brown or red color)
• Weakness
• Pale gums
• Panting
• Rapid heart rate

If you notice any of these symptoms in your dog, call the vet immediately. This is an emergency.

Let the vet know how much onion your dog has eaten and about what time this happened. And if the onion was included in a dish, then be sure to write down the other ingredients if you know them. It’s possible some of these may also be toxic to the dog (such as garlic).

The prognosis is best for dogs who receive prompt medical treatment. And in the future, remember to keep onions and other foods out of your dog’s reach!
