# Why Is My Dog Drooling Excessively? — Quick answer

PETHEALTH+ (https://pethealth.org.uk/uk-pet-questions/why-is-my-dog-drooling-excessively): Why Is My Dog Drooling Excessively? — Quick answer. Some breeds drool more by design — Mastiffs, Bloodhounds, and Saint Bernards are normal slobbers. Sudden heavy drooling in any dog — especially with pawing at the mouth, vomiting, or distress — may signal nausea, dental pain, toxin exposure, or heatstroke. A change from your dog's usual amount always deserves attention.
