My 4 kg Chihuahua ate a tablespoon of salsa and now has diarrhoea — is that from the salsa?

Short answer

Yes, the salsa could easily be the cause, especially for a small dog. The combination of onion, garlic, and chilli peppers in salsa can irritate a dog's digestive tract, leading to gas, stomach cramps, and diarrhoea. Some dogs may also show signs of a food intolerance, like itchy skin, even without the classic poisoning symptoms. Offer plain water and a bland diet for a day or two, and contact your own vet if the diarrhoea persists or your dog seems lethargic.

Salsa — Food safety facts

Onion, garlic and chilli together. All three cause problems.

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

Salsa 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.

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.
