My 7 kg dog with a sensitive stomach ate a handful of plain roasted pumpkin seeds. Could this give him diarrhea?

Short answer

It could, especially if he's not used to them. The fiber and oils in pumpkin seeds, while generally safe, can upset a sensitive system and cause loose stools or gas. Watch his next bowel movement for any change in consistency. Make sure he drinks water. If diarrhea develops, skip his next meal and offer plain boiled chicken and rice once his stomach settles. Next time, try just two or three seeds to see how he tolerates them. Call your own vet if the diarrhea lasts more than a day or he seems lethargic.

Pumpkin seeds — Food safety facts

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

Plain unsalted pumpkin seeds are safe in small amounts.

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

Pumpkin seeds 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

A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.

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

Pumpkin seeds 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.
