There are many upper respiratory viruses and bacteria that can cause sneezing in dogs. These dangers are in much higher concentrations at boarding kennels. The good news is that for adult healthy dogs, upper respiratory infections are usually mild and pass quickly.
Foreign bodies and allergies – If your dog’s symptoms get worse (lethargy, not eating) or you see mucus or yellow-green discharge, contact your veterinarian.
Kennel cough – This results from any of a multitude of viruses and bacteria. Dogs exhibit various coughing symptoms, from a mild hack to a very strong cough (which may sound like choking). If you suspect kennel cough in your dog, see your veterinarian.
