Why is my dog coughing and gagging after drinking water?
Why is my dog coughing and gagging after drinking water may be caused by throat irritation, kennel cough, airway inflammation, allergies, collapsing trachea, heart disease, or fluid/foam from nausea or respiratory irritation. Coughing that repeats, produces white foam, follows exercise, or appears with breathing changes should be checked by a veterinarian.
