What happens if a dog eats diesel?

A dog eating diesel may show: first, diesel is strongly irritating and affects the mouth and gut lining, causing drooling, diarrhea, nausea, and vomiting. Second, swallowing diesel may irritate the airways, causing cough, breathing difficulty, and pulmonary edema.

Finally, some diesel components (like aromatics and sulfides) are neurotoxic and may cause nerve signs such as tremors, seizures, and coma.
