Dogs that have illnesses like bronchitis or pneumonia may cough quite a bit and have chest congestion. Expectorants are sometimes helpful, as they can get rid of excess mucus stuck in the lungs.

Function
-
According to the University of Michigan Health System, expectorants loosen and then expel mucus when a patient coughs.
Types
-
The "Merck Veterinary Manual" says guaifenesin (glyceryl guaiacolate) is an expectorant drug. Pharmacies sell it over the counter under various brand names. Vetinfo.com lists ginger, kasni (chicory) and yerba santa as natural expectorants, which owners can find at health food stores.
Dose
-
With the correct dose, side effects of expectorants are minimal. A veterinarian will determine the dose after evaluating the dog's condition, medical history and weight.
Consideration
-
Drinking plenty of water helps expectorants do their job, so owners need to monitor their dog's water intake.
Warning
-
Owners must contact their vet immediately if their dog's condition worsens. Do not give more expectorant than directed.
