A bunch of green onions on a red background with dog and cat outlines: hazardous to both species

Already eaten — what now?

For dogs and cats

Urgent help needed

Call a veterinarian immediately even if your pet looks well. Give the species, weight, time, approximate amount, which part was eaten and whether it was fresh, cooked or dried. Keep the remaining dish, recipe or package. Do not induce vomiting or give home remedies unless a veterinarian specifically instructs you to. Travel immediately for weakness, pale or yellow gums, rapid breathing, dark urine, poor coordination or collapse.

Check the variant

Variants and ingredients

Fresh green onionFor dogs and cats: Dangerous · Urgent help needed

The white base, roots and green leaves, whole or chopped.

For dogs and cats

Conditions and restrictions

Do not offer green onion or add it to homemade food, broth or treats. Keep fresh onion and dishes containing it out of reach.

Benefits

There is no dietary benefit that justifies the risk.

Risks
  • Sulfur-containing oxidants in Allium can damage red blood cells and cause Heinz body haemolytic anaemia.
  • Vomiting and diarrhoea may occur. Weakness, pale or yellow gums, rapid breathing, dark urine and collapse can appear later.
  • Repeated small exposures also matter because injury can accumulate, and cats are particularly susceptible.

Conditions and restrictions

Check the ingredients of seasonings, stock mixes, baby food and prepared dishes. Keep concentrated forms sealed and out of reach.

Benefits

There is no dietary benefit that justifies the risk.

Risks
  • Sulfur-containing oxidants in Allium can damage red blood cells and cause Heinz body haemolytic anaemia.
  • Vomiting and diarrhoea may occur. Weakness, pale or yellow gums, rapid breathing, dark urine and collapse can appear later.
  • Dried and powdered forms are concentrated, so a small volume may contain more onion than it appears.
