CAN DOGS EAT ONION POWDER?
Onion powder is approximately 5x more concentrated than fresh onion — a fraction of a teaspoon is enough to cause hemolytic anemia in dogs.
Can Dogs Eat Onion Powder?
Why?
Dehydration concentrates all of onion's organosulfur compounds into a smaller volume. This means onion powder presents a substantially higher risk per gram than fresh onion. A teaspoon of onion powder contains the equivalent toxin of a small whole onion.
Onion powder is a near-invisible ingredient in many human foods: seasoning packets, soup stock, canned broth, baby food, freeze-dried meals, and processed meats all commonly contain it. Dogs who receive food scraps or "natural" baby food have developed hemolytic anemia from what their owners believed was a safe food.
How much is dangerous?
1/4 teaspoon of onion powder can be toxic for a 20-lb dog. Any detectable amount warrants concern.
What are the symptoms?
- pale gums
- lethargy
- weakness
- rapid breathing
- reddish-brown urine
- loss of appetite
- collapse
What should I do?
Contact your vet. Blood count evaluation is needed. Severe cases require IV fluids and possibly a blood transfusion.
