How much ground black pepper is too much for my 6 kg Shih Tzu to eat before it irritates his stomach?

Short answer

A light sprinkle of black pepper is harmless for most dogs, but your small Shih Tzu is more sensitive to larger amounts. Anything more than a pinch between your fingers could irritate his stomach and lead to vomiting or diarrhea. When seasoning your dog's food, stick to just a few ground grains — a full teaspoon is far too much for a dog your size. Watch for signs of gastrointestinal upset over the following hours, and call your vet if symptoms persist or worsen.

A light sprinkle is harmless. Large amounts irritate the stomach.

Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.

Black pepper is not poisonous to dogs, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.

If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.
