Combined with its antimicrobial and antiviral properties, mullein proves to be excellent in treating kennel cough and various other forms of respiratory distress in dogs and other animals. A glycerin tincture can be given directly into the mouth (1-2 ml. per 20 lbs of animal's weight, twice daily).

Topically, the astringent and antimicrobial properties of the leaves are ideal for use treating minor wounds and insect bites. It speeds healing and is soothing to inflamed areas. Just mash up a few fresh or dried leaves with some water and apply the poultice to the affected area.
