Onions, a staple in many human cuisines, are toxic to dogs. Can you wipe off onions and give food to dogs? The answer is a resounding no. Even a small amount of onion, whether raw, cooked, powdered, or even wiped off food, can cause serious health problems in our canine companions. This article dives deep into the dangers of onions for dogs, explaining why they are toxic and what to do if your dog accidentally ingests them.
Why are Onions Toxic to Dogs?
Onions, along with garlic, chives, and leeks, belong to the Allium family. These plants contain compounds called thiosulphates, which damage red blood cells in dogs, leading to a condition called hemolytic anemia. This means the red blood cells are destroyed faster than the body can replace them, resulting in a decreased ability to carry oxygen throughout the body.
Understanding Hemolytic Anemia in Dogs
Hemolytic anemia can manifest in various symptoms, ranging from lethargy and weakness to vomiting, diarrhea, and pale gums. In severe cases, it can lead to jaundice, rapid breathing, increased heart rate, and even death. The severity of the reaction depends on the amount of onion ingested, the size of the dog, and the individual dog’s sensitivity.
What to Do if Your Dog Eats Onions
If you suspect your dog has eaten onions, contact your veterinarian immediately. Even if your dog isn’t showing symptoms, prompt veterinary attention is crucial. The veterinarian may induce vomiting or administer activated charcoal to absorb the toxins.
Symptoms to Watch For
- Lethargy
- Weakness
- Vomiting
- Diarrhea
- Pale gums

Safe Alternatives to Onions for Dog Food

You can also find commercially available dog food and treats that are specifically formulated to be safe and appealing to dogs.

Can Dogs Eat Food Where Onions Have Been Cooked?
No, even if onions have been cooked or the residue has seemingly been wiped off, the food is still unsafe for dogs. The thiosulphates remain present even after cooking and can still cause harm. It’s best to avoid feeding your dog any food that has come into contact with onions.
Can Dogs Eat Onion Powder?
Onion powder is even more concentrated than fresh onions, making it even more dangerous for dogs. A seemingly small amount of onion powder can contain a significant amount of thiosulphates. Always check ingredient lists carefully and avoid any food products containing onion powder if you plan to share them with your furry friend.
