We're having a BBQ party with leeks on the grill. How can I stop my 15-kg curious dog from grabbing some?

Short answer

Be very proactive, as leeks are just as toxic as onions and garlic to dogs. Keep your dog on a leash or in a separate, secure room during the party, away from the food area. Clearly inform all guests that leeks are poisonous to pets and to not feed any scraps. Have a stash of safe dog treats ready to redirect your dog's attention. If your dog does manage to eat any amount, contact your vet or the ASPCA Animal Poison Control Center at 888-426-4435 immediately, as even a small bite can cause red blood cell damage.

Leek & chives — Food safety facts

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

Toxic, same family as onion and garlic. Causes red blood cell damage and anemia.

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

Leek & chives 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.

Leek & chives 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.
