Hello there! I'm Dr. Emily, a veterinarian with over 15 years of experience. I specialize in small animal care, including canine health. It's great to hear from you.

Onions, along with other members of the allium family like garlic, leeks, and chives, can be toxic to dogs. This is because they contain a compound called N-propyl disulfide, which can damage red blood cells and lead to hemolytic anemia.

**Symptoms of onion poisoning in dogs can vary depending on the amount ingested and the dog's size, but they usually appear within 12-72 hours.** Here are some of the most common signs:

* Gastrointestinal upset: This can include vomiting, diarrhea, and loss of appetite.
* Weakness and lethargy: The dog may seem tired and less energetic than usual.
* Pale gums: This is a sign of anemia, which can be caused by the destruction of red blood cells.
* Increased thirst and urination: This is due to the body trying to flush out the toxins.
* Rapid breathing: This can be a sign of difficulty breathing due to anemia.
* Dark urine: This is caused by the breakdown of red blood cells.
* Increased heart rate: This is the body's response to a lack of oxygen in the blood.
* Coma: In severe cases, the dog may become unconscious.

**If you suspect your dog has eaten onions, it's important to contact your veterinarian immediately.** The sooner you seek treatment, the better the chances of a full recovery.

**Here are some tips for preventing onion poisoning in dogs:**

* Keep onions out of reach of your dog. This includes storing onions in airtight containers or high shelves where your dog can't access them.
* **Be careful when preparing food with onions.** Make sure to dispose of onion scraps properly and avoid letting your dog eat any food that contains onions.
* **Supervise your dog around other people who may be eating onions.**
* Choose dog treats that are onion-free.
* **Educate your family and friends about the dangers of onions to dogs.**

**Remember that even small amounts of onions can be toxic to dogs.** It's always better to err on the side of caution and keep onions out of your dog's reach.
