My 3-month-old, 2 kg puppy chewed and swallowed a small piece of raw shallot — is this extra risky for a puppy?

Short answer

Yes, puppies are at higher risk. Their small body size means even a tiny amount of concentrated allium toxin can damage red blood cells, leading to anemia. Signs like weakness, pale gums, or red-tinged urine may take 1-3 days to appear. Call your vet or an emergency poison line now — do not wait for symptoms. Keep the puppy calm and hydrated. The vet may induce vomiting if it was very recent, or provide supportive care like IV fluids. Store all onions, shallots, and garlic securely where a curious puppy cannot reach them.

Shallot — Food safety facts

Do not feed · Dogs · full breakdown on the linked food page

Allium toxicity — more concentrated than onion. Keep them out of reach.

Dogs and cats carry the same rating (Do not feed), so the notes below hold for either pet.

Shallot should not be given to dogs at all. Even a small amount can do harm, so there is no portion small enough to be safe.

Do not induce vomiting and do not give milk or oil to “dilute” it. Note the food and roughly how much was eaten, then call your vet or a pet poison hotline and follow their advice on whether to bring the pet in straight away.

Why these cautions matter

Garlic and onion damage a pet's red blood cells and can bring on anaemia. Signs are often delayed for several days, so looking fine straight afterwards does not rule it out.

Shallot has no place in everyday feeding: keep the rest of the day's food unchanged after this and watch the next walk and the stool that comes with it.
