In recent weeks there has been a lot of news about this "mystery respiratory illness" in dogs. Here in the US, it has been spreading and at this point there are no specific testing to confirm if you dog has it. It is described as an atypical canine infectious respiratory illness.

Here are some of the symptoms (that do mimic Kennel Cough - Bordetella or dog influenza):
- coughing
- sneezing, runny nose
- fever
- lethargy
- decreased appetite
- discharge from the eyes
- others have more severe signs or pneumonia

Be sure your dog is fully vaccinated. Consult with your veterinarian about vaccines for your dog. Vaccines for respiratory disease include those for “kennel cough” (which only protects against one of the many bacteria that cause this disease) and canine influenza if your dog goes where there are other dogs (groomer, boarding, day care, play groups, dog parks, dog shows, etc.). It is good to ask that the places like those listed where you bring your dog require vaccinations for dogs to participate.
If your dog becomes ill with respiratory signs such as coughing or sneezing, watch closely, keep away from other dogs (i.e. don’t attend day care, don't take them to stores, etc.), and if your dog is lethargic, not eating, or the cough persists/worsens seek veterinary care.
