Kennel cough, also known as canine infectious tracheobronchitis, is a highly contagious respiratory infection that affects dogs. It is caused by a variety of bacteria and viruses, and it is spread through the air viaing, sneezing, or close contact with an infected dog.
Kennel cough can cause a variety of symptoms, including a hacking cough, sneezing, runny nose, and lethargy. In severe cases, it can lead to pneumonia or other respiratory complications. While kennel cough is not typically fatal, it can be a serious illness, especially for young puppies and dogs with weakened immune systems.
