One of the most common dog diseases is kennel cough, similar to the common cold.
Caused by a variety of different viruses, kennel cough is the canine equivalent to the common cold.
Gastroenteritis (inflammation of the stomach and the intestine) is the second most common illness in the United States, after the common cold.
Because the majority of coughs are related to the common cold or influenza, most will end in seven to 21 days.
Fortunately, the bacteria that cause meningitis are not as contagious as the common cold or the flu, and they are not spread by casual contact or by simply breathing the air where a person with meningitis has been.
