My bulldog had a cough for a week this time no fever slight watery sometimes white discharge from nose, took him to the vet today and found out one lung had bronchitis and the other pneumonia. Did they give your dog antibiotics? This is the second time Hooch has had pneumonia both times started out as coughing. Did they do a chest x-ray? My vet said when I told her about the slight nasal discharge she knew it was pneumonia and confirmed through x-ray. She said she may not have given him a chest x-ray if his only symptom was a cough..
