Yes, onions are toxic to dogs. Onions, along with garlic and leeks, belong to a plant group called alliums, all of which are poisonous to dogs and cats.
Why are Onions Toxic to Dogs?
The toxicity stems from compounds called disulphides and thiosulfinates present in alliums. These toxins damage red blood cells, leading to anemia. This damage can be significant, especially with larger ingestions or repeated exposure.
Symptoms of Onion Poisoning in Dogs
If your dog ingests onions, watch for these symptoms:
- Vomiting
- Diarrhea
- Reduced appetite
These symptoms can indicate a more serious health issue requiring veterinary attention.
What to Do if Your Dog Eats Onions
If you suspect your dog has eaten onions, contact your veterinarian immediately. The sooner treatment begins, the better the outcome. The severity of the reaction depends on several factors, including the amount of onion consumed, the size of the dog, and the dog's overall health.
