My 10 kg dog ate a spoonful of hemp hearts that were left in a bowl for a week. Is this safe?

Short answer

Yes, this is generally safe. The main risk from old hemp hearts is spoilage, which could cause an upset stomach. Watch your dog for vomiting, diarrhea, or loss of appetite over the next day. If you see any of these signs, contact your regular veterinarian.

Shelled hemp hearts are safe in small amounts. Hemp leaves and flowers are not.

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

Hemp 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.
