My 6 kg west highland white terrier ate papaya with the seeds left in — will the seeds cause problems beyond an upset stomach?

Short answer

The flesh itself is safe and gentle on the stomach, but the seeds contain traces of cyanogenic compounds and should always be removed before feeding. A few seeds in a 6 kg dog are unlikely to cause serious poisoning, but they can irritate the gut and lead to vomiting or diarrhoea on top of whatever the fruit already caused. Stick to seedless ripe papaya in small pieces as an occasional treat, and call your vet if she shows persistent vomiting, lethargy, or refuses food for more than 24 hours.

Papaya — Food safety facts

Safe to share · Dogs · full breakdown on the linked food page

Ripe flesh is safe and gentle on the stomach. Remove the seeds — they contain traces of cyanogenic compounds.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Papaya is not toxic to dogs. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter

Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.

Papaya can stay on the rotation, but only as an extra mouthful: keep the rest of the day's food unchanged and watch the next walk and the stool that comes with it.
