In Los Angeles County, health officials have reported 10 cases of a mysterious illness that is affecting dogs. The Los Angeles County Department of Public Health is currently conducting an investigation to determine the source of the illness and how far it has spread throughout the county. The respiratory illness, known as Atypical Canine Infectious Respiratory Disease, is characterized by coughing, nasal discharge, sneezing, and lethargy.

Despite displaying symptoms similar to those of common viruses and bacteria, dogs are testing negative on the respiratory panel used for these conditions. As part of the investigation, county health officials are contacting the owners of sick dogs in an effort to identify the source of the infection. Additionally, they are working with federal and state agencies to coordinate the investigative efforts.

If a dog is showing symptoms of the illness, the Department of Public Health is advising owners to contact their veterinarian and isolate their dog at home for a minimum of 28 days. Furthermore, dogs that have been in contact with an infected dog should undergo a 14-day quarantine at home, away from other dogs.
