A dog’s nose always humming after recovering from a cold is a sequelae of a viral infection, or it could be that the illness was so severe during the course of the flu that it caused organic damage to the respiratory system. When fibrosis or organic damage occurs, then there is a high probability that the dog will not recover or will not recover. Dogs with chronic rhinitis may also make a humming and puffing sound, which may cause more serious consequences if left untreated. Therefore, once a dog is found to be suffering from chronic rhinitis, it is necessary to seek medical attention in a timely manner so as not to delay the condition.
