Pneumonia in dogs can usually be cured in 1 to 2 weeks, but the treatment time is also affected by the dog's constitution and the cause of the disease. In serious cases, it may take about a month to be cured. If the bacterial pneumonia is caused by a cold, it can be cured in about two weeks. If the pneumonia is caused by fungi or mycoplasma, the treatment time will take about a month. During the treatment period, attention should be paid to supplementing the dog's nutrition and strengthening its physical condition to facilitate recovery.
