What Do You Do If Your Dog Ate an Onion?

People often assume that they can give their dogs almost anything that they eat. However, there are many foods that are safe for humans that are very dangerous for dogs. One such food is onions, which are toxic to dogs. Therefore, this is a food that you should avoid feeding to your pet. Sometimes, dogs can steal food, and this can make it difficult to monitor exactly what they have eaten. It also means that they may eat onion despite you avoiding feeding them this ingredient. The following is an overview of why onions are dangerous for dogs and what you should do if your dog eats onion.

Why Is Onion Toxic for Dogs?

According to The Dogington Times, onions are toxic to dogs because they contain a substance called thiosulfate. Dogs cannot digest this substance because they do not have the right enzyme in their body to digest this substance. Both raw and cooked onions contain this substance, so you should avoid feeding them both. Onions also contain organosulfur, which is a compound that leads to a condition called toxicosis. This condition is a form of poisoning.

How Serious Is a Dog Eating Onions?

Some foods, such as grapes, are extremely dangerous for your dog even in small quantities. That is not the case with onions, as the severity of onion poisoning depends on the quantity eaten. If your dog has stolen a slice of pizza and it has a couple of onion slices on top, then it is unlikely that your dog will suffer any ill effects. However, if your dog eats a larger quantity of onion or it eats onions regularly, then it is potentially serious.

What Symptoms Are Caused by Eating Onions?

If your dog eats onions, then the symptoms they suffer can vary and the severity will depend on the amount eaten. Some of the symptoms a dog can potentially experience after eating onions include:

  • Asthmatic attacks
  • Weakness
  • Dermatitis
  • Allergies
  • Dark urine
  • Anemia
  • Diarrhea
  • Vomiting
  • Liver damage
  • Increased heart rate
  • Heinz Body Anemia

The biggest concern when a dog eats onions is that they will develop Hein Body Anemia, says Canna-Pet. Many of the symptoms from which a dog suffers after eating onions are as a result of this condition, which destroys a dog’s red blood cells.

What You Should Do If Your Dog Eats Onions

Prevention is better than a cure, so you should try to keep any foods that contain onions out of reach of your dog. Also, make sure that your dog cannot access the trash can to steal leftover food. However, even if you think you have been careful to keep onions out of the way of your dog, it is still possible that they may accidentally eat some onion.

If your dog has only eaten a small amount of onion, then it is unlikely to cause them any significant harm. Dogs are unlikely to eat any onions at all because most do not like the taste of them. However, if you suspect that your dog has eaten a large amount of onion, then you will need to seek the advice of a veterinarian as soon as possible, says Dogster.

At the appointment, the veterinarian will examine your dog and ask you about any symptoms they have displayed. This will allow them to evaluate your dog’s condition and decide whether your dog needs treatment or not. The vet may also take a blood sample to check your dog’s red blood cell count to make sure the dog is not suffering from Heinz Body Anemia.

Treatment for Onion Toxicity

There are several treatment options if your dog has eaten onions, and your veterinarian will decide on the best option based on the amount of onion eaten and the severity of the symptoms from which your dog is suffering. The first option is for your vet to induce vomiting in your dog to eliminate onions from their digestive tract. Another option is for them to give your dog activated charcoal, which absorbs the toxic elements of the onion and reduces the damage that they do to your dog.

It is possible that your vet may also give your dog fluids to maintain their hydration levels. If they believe that your dog has liver damage, then it is possible that your dog may also need a blood transfusion. Furthermore, your dog may need medication to treat some of the symptoms they are experiencing.

Can Dogs Recover from Onion Poisoning?

A dog who has only eaten a small quantity of onion should recover quickly. If they have eaten a larger amount of onion, they should make a full recovery if you have taken them to a vet quickly and they have received treatment for their symptoms. If your dog has underlying health conditions, the effects of onion toxicity are potentially worse. In serious cases of onion toxicity in dogs with other health problems, it is possible that the toxicity is fatal. However, fatalities from onion poisoning are very rare.

Dogs and Onions – The Bottom Line

One of the foods that you should not give your dog is onions, in both raw and cooked forms, as it contains a toxic substance that dogs cannot digest. Although small quantities of onions are unlikely to do your dog any harm, larger quantities can lead to your dog suffering from onion toxicity. The severity of this depends on how much onion your dog has eaten. The biggest concern is that it will lead to your dog suffering from Heinz Body Anemia. In most cases, onion toxicity is not fatal as there are several treatment options for the symptoms. Therefore, it is essential that you take your dog to the vet as soon as you realize that they have eaten onions so that treatment can begin as soon as possible. If your dog receives treatment quickly, it is likely that it will make a full recovery.
