Have you ever found yourself in a panic when your furry friend accidentally consumed something they shouldn't have? If your dog has ingested onion, this article is here to provide you with some guidance on what to do next. How Pet Care will dig into this topic to ensure the well-being of your beloved pet.
What To Do If A Pet Eats Onion
When it comes to onion ingestion, immediate action is crucial. Here are some steps you should take:
- Seek Veterinary Assistance: Contact a vet as soon as possible to induce vomiting and prevent toxin absorption.
- Monitor Blood Levels: If the onion has already been absorbed, daily blood tests are necessary to monitor for anemia.
- Even Small Amounts Matter: It's important not to underestimate the potential harm caused by even a tiny amount of onion. Pets vary in sensitivity, and the toxic dose for them is relatively low.
Now let's delve deeper into this issue.
Onion consumption ranks third among common poisoning cases seen by veterinarians in Adelaide, highlighting the seriousness of this matter for pet owners like yourself. Surprisingly, it's not raw onions that pose a significant risk but rather cooked onions used in various dishes and leftovers that become enticing meals for our pets without warning them about the potential dangers they contain.
How Much Onion Is Dangerous?
As little as 2.5g of onion per kilogram of body weight can have severe effects on most dogs. For instance, a Jack Russell Terrier weighing just 15g could experience serious consequences from such an amount. Similar results have been observed with garlic and other related vegetables*. Here are two essential facts regarding onion ingestion:
- Induce Vomiting: All dogs who consume onions should be made to vomit since susceptibility varies among individuals.
- Cumulative Exposure: The lower line on the graph at the top demonstrates that dogs recover slowly. Introducing more onion during this period can cause further damage and increase the risk.
The study used 5g/kg of dehydrated onion, which is likely equivalent to cooked onion. Fresh onions would weigh more, but given that some dogs developed life-threatening anemia from this lower dose, it's evident that the hazardous threshold is even lower.
Is Garlic Toxic To Pets?
Yes, it is. Experience has shown that all members of the onion family are potentially dangerous to pets. This includes not only different types of onions but also garlic, leeks, spring onions, shallots, and even chives.
Why Are Onions Poisonous?
It may seem strange that humans can consume onions without issue while many other animals cannot. The reason behind this lies in antioxidants.
Onions (both cooked and raw) contain sulfur compounds that cause oxidative damage. Unfortunately, the red blood cells in dogs and cats have a low antioxidant capacity. When these factors come together, disaster ensues.
Consequently, when dogs or cats consume onion-laden food items, their red blood cells become targets of chemical attacks with two critical consequences:
- Deactivation of Hemoglobin: The molecule responsible for oxygen transport is rendered ineffective.
- Ruptured Cell Walls: Red blood cells get destroyed as their cell walls rupture.
As a result of these reactions within the body's system emerges anemia—a condition characterized by reduced ability to deliver oxygen throughout the body.
Symptoms Of Onion Poisoning
Typically appearing after 1 to 3 days when anemia sets in, signs of onion poisoning include:
- Lethargy
- Weakness
- Labored breathing
- Pale gums
- Collapse
You may also notice changes like red urine and yellow eyes due to pigment release resulting from the destruction of red blood cells.
Treatment Of Onion Poisoning
If your dog has consumed onion within the last hour, inducing vomiting can help mitigate the damage. However, after this timeframe, it is likely that some of the toxin will have already been absorbed.
In such cases, vomiting may still be beneficial followed by administering activated charcoal. Keep in mind that there is no specific antidote for onion toxicity once it enters the bloodstream.
Regular blood tests are required to monitor the affected dogs and assess their progress. Some individuals might need oxygen support or transfusions; however, most dogs recover without complications.
Do note that comments (if open) will appear within 24 hours.
