Chili pepper — Food safety facts
Do not feed · Dogs · full breakdown on the linked food page
Capsaicin causes severe mouth pain, drooling, vomiting and stomach irritation.
Dogs and cats carry the same rating (Do not feed), so the notes below hold for either pet.
Chili pepper 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.
Chili pepper 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.
