Can my 6 kg beagle get sick from eating fresh dill that was left out overnight in summer heat?

Short answer

Fresh dill itself is safe for dogs in small amounts, but once it has been left out overnight in warm weather, bacterial growth becomes the real concern rather than the herb itself. A 6 kg beagle who nibbled a few leaves is unlikely to develop serious problems, but watch for vomiting, diarrhea, or lethargy over the next 24 hours. If any of those signs appear, call your vet — otherwise plain fresh dill in modest amounts is fine and spoiled dill is just a gastrointestinal risk, not a toxicity issue.

Dill — Food safety facts

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

Safe in small amounts, fresh or dried.

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

Dill 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.
