Why Does a Dog Keep Rubbing Its Nose on the Ground

A dog rubbing its nose on the ground may have a cold (nasal discharge blocks breathing), a foreign object in the nose (pollen, dust, grass seed — causes sneezing), nasal skin disease (mites, bacteria, fungus, eczema — itchy, with hair loss), or simply be investigating an interesting scent on the floor. Treat the cause: cold medicine, remove the object, medicate the skin, or just redirect its attention.
