Short answer
No, fresh dill is safe for dogs and rarely causes diarrhea. Some sensitive dogs might get mild stomach upset if they eat a large amount. Offer just a pinch at first to check their tolerance. If loose stools occur, skip it next time and stick to their regular food. Call your vet if diarrhea lasts more than a day or seems severe.
