Onions are a common ingredient in many dishes and are a popular choice for adding flavor to food. But can dogs eat onions?
The short answer is no. Onions, in any form (raw, cooked, dehydrated), are toxic to dogs and can cause a range of health problems. In this article, we’ll explain why onions are dangerous for dogs and what you should do if your dog has eaten them.
What Are Onions?
Onions are a type of plant in the Allium family, which also includes garlic, leeks, and shallots. Onions are cultivated and eaten around the world and are used in a variety of dishes.
Onions are made up of several layers, each of which contains a different compound. These compounds are what give onions their flavor, aroma, and health benefits.
The outermost layer of the onion contains a compound called thiosulfate, which is toxic to dogs. The inner layers of the onion contain other compounds, such as flavonoids and organosulfides, which are also toxic to dogs.
Why Are Onions Bad For Dogs?
Onions are toxic to dogs because they contain a compound called thiosulfate, which is toxic to dogs. This compound is found in all parts of the onion, including the flesh, skin, and juice.
When a dog eats onions, the thiosulfate is broken down in the dog’s digestive system and absorbed into the bloodstream. The thiosulfate then enters the red blood cells, where it damages the cell walls and prevents them from carrying oxygen. This can lead to anemia, which can be fatal if left untreated.
In addition to anemia, onions can also cause other health problems in dogs, such as vomiting, diarrhea, abdominal pain, and lethargy.
How Much Onion Is Too Much?
The amount of onion that is toxic to a dog depends on the size of the dog and the amount of onion consumed. Generally, a small amount of onion is enough to make a dog sick, but the larger the dog, the more onion they can tolerate.
In general, a dog should not eat more than 0.5% of their body weight in onions in a single day. For example, a 10-pound dog should not eat more than 0.5 ounces of onion in a single day.
What Should I Do If My Dog Eats Onions?
If you think your dog has eaten onions, you should take them to the vet immediately. The vet will be able to diagnose your dog and provide treatment, which may include fluids, medications, and blood transfusions.
It’s important to note that the effects of onion toxicity can take several days to show up, so you should take your dog to the vet even if they seem fine.
How Can I Prevent My Dog From Eating Onions?
The best way to prevent your dog from eating onions is to keep them out of reach. This means keeping onions off countertops, out of trashcans, and away from other places where your dog might be able to get to them.
You should also be careful when preparing meals and make sure that any onions you use are safely stored away from your pet.
Finally, it’s important to be aware of the foods you are feeding your dog and make sure that they do not contain onions. If a food does contain onions, you should not feed it to your dog.
