Respiratory Illness Affecting Dogs in Various States. Here Are The Signs.

A highly contagious upper respiratory infection is spreading in dogs across the country.

Typically, respiratory infections in dogs cause mild-to-moderate symptoms, including coughing, sneezing, nasal and eye discharge, and lethargy, that last a week or two. With this new illness, however, dogs are developing a cough that persists for six to eight weeks. Some dogs have developed pneumonia that does not respond to antibiotics, and a small percentage have died.
