Are Onions Poisonous To Cats Or Dogs?
You may be surprised to learn that dogs and cats can become poisoned by all parts of the onion, including the leaves, flesh, skin, and juice, whether cooked or uncooked. And, cats and dogs are not just poisoned by the typical onion, but all vegetables in the onion family! That’s right; the entire onion family, whether they’re dehydrated or powdered, can deplete a pet’s red blood cells and lead to anemia. How can such a commonly used veggie be so dangerous to our pets? It’s the N-propyl disulfide, a toxic chemical found in onions. This onion component causes dogs and cats to lose their red blood cells, resulting in anemia. The toxin causes oxidative damage by sticking to the oxygen molecules in their red blood cells. Any onion (white, yellow, or green) can produce onion toxicosis. Dogs and cats should avoid eating any of the following Allium family or onion genus vegetables:
ChivesGarlicLeeksOnionsScallions
All of these can be deadly to dogs and cats if consumed in high quantities or nibbled on repeatedly over time. In fact, garlic is thought to be five times as harmful to cats and dogs as onions! Preparations like soup mixes containing onion or garlic powder can potentially be deadly if ingested in large quantities.
How Much Onion Is Bad For My Dog Or Cat?
This depends on your dog’s weight. Cats are at risk if an onion contains more than 1 gram per 5 pounds of body weight. When a dog consumes more than 0.5 percent of its body weight in onions in one sitting, toxicity ensues. A 30-pound dog, for example, would need to eat about 2.5 ounces of onion or garlic to become ill. Simply put, a small bit of onion, garlic, or other toxic allium food can quickly poison a pet.
How Long Does It Take For Onion To Affect Dogs?
Onion-related symptoms typically begin to develop one to three days after a pet eats an onion. It is at this point that the effects of damaged and dying red blood cells can be seen in the body. Veterinarians will most likely induce vomiting if your pet has eaten onions within the past 1 to 2 hours. However, never attempt this yourself as it can further complicate things when not done right or unnecessary. Sometimes, activated charcoal will be given to the animal by a veterinarian to help it absorb poisons if it’s been longer than a few hours.
Signs Of Onion Poisoning In Pets
Symptoms can take up to a week to manifest, so keep this in mind. There are several signs and symptoms of a digestive system problem, including:
Loss of interest in fooddrooling
Some of the more serious side effects pertaining to red blood cell destruction include:
Bloody UrineElevated Heart And Respiration RateFatigueHeavy BreathingPale GumsVomiting BloodWeakness
Your pet should be taken to the vet immediately if they ingested onion and exhibit any of the following signs noted above. In severe cases, your pet may require oxygen support, blood transfusion, and intravenous hydration.
In Conclusion
It’s important to remember that all onions are poisonous to cats and dogs. There are no onions that are safe, whether they are white, yellow, red, or green. It also doesn’t matter whether the onion is cooked, raw, or in powdered form. Because the disulfide molecule is not gone when an onion is cooked, it is just as dangerous to your dog or cat companion.
