Black Pepper
CautionBlack pepper has no established toxic dose in dogs, but piperine is an irritant. A pinch on a steak is not an emergency; inhaled powder causes sneezing and coughing, and a large amount brings vomiting and diarrhea. Never sprinkle it as a deterrent.

More about this food
The heat in black pepper comes from piperine, a different compound from the capsaicin in chili peppers, and it is not a toxin with an established lethal dose in dogs. A dog that ate a peppered scrap of steak is not headed for the emergency room. Piperine is, however, a mucosal irritant, and larger amounts produce real signs.
The most common reaction is gastrointestinal. Drooling and lip smacking first, then vomiting or loose stool within a few hours, and abdominal discomfort if the dog cleaned out a spilled pepper grinder or ate a heavily peppered dish. The second is respiratory. Inhaled powder makes dogs sneeze and cough and feel short of breath. Pet Poison Helpline describes exactly this with cinnamon, another powdered spice: dogs that inhale it can cough, choke, have difficulty breathing and develop bronchospasm. Grinding pepper over a dog's head, or leaving an open shaker where a dog can nose into it, is worth avoiding for that reason alone -- and more so with a flat-faced breed.
In practice dogs rarely eat pepper by itself. It arrives on something: a peppered roast, fries, alfredo, a rotisserie chicken, a ramen packet. The AKC's feeding guidance is that you should never add seasoning or salt to food for a dog, and never feed anything cooked with onions or garlic, since those are toxic. Whether you have a pepper problem or a dinner problem depends on what else was in the dish.
One more thing: do not sprinkle pepper on trash bags, cords or shoes to keep a dog away. It hurts if it reaches the eyes or nose, and it teaches nothing except that the kitchen is unpleasant.
For a small taste, rinse the mouth, offer water and watch. Most dogs settle within a few hours. Call your veterinarian if coughing does not stop or breathing looks labored, if vomiting repeats, if the belly is painful, or if the peppered food also contained onion or garlic. The ASPCA Animal Poison Control Center is at (888) 426-4435. Do not induce vomiting at home.
Frequently asked questions
- My dog ate a peppered piece of steak. Should I worry?
- Not about the pepper at that amount. You may see drooling or one bout of vomiting, so offer water and watch. If the meat was seasoned with garlic or onion powder, that part matters more, so check the rub and tell your vet.
- My dog sniffed pepper and has been sneezing since. Is that dangerous?
- Powdered spice irritates the airway, which is why the sneezing and coughing started. Move your dog to fresh air and offer water; it usually settles quickly. Persistent coughing or labored breathing, especially in a brachycephalic breed, needs a vet.
- Can I use pepper to keep my dog away from the trash?
- No. It can burn the eyes and nose, and it does not teach the behavior you want. Manage the environment instead: a lidded can, a closed door, and a chew your dog is allowed to have.
