A pustule on a dog's belly may be caused by a wound infection, pus, or a mosquito bite, or a hernia. If parents cannot determine what caused the pustule, it is best to take the dog to the hospital. The doctor will come to check. If it can be judged that it is suppuration, it needs to be debrided in time and disinfected to prevent the dog from licking it.

Tip:

When raising dogs, we need to observe the dog's physical condition every day to see if there are any wounds or abnormalities, so that early detection and early treatment can prevent the situation from getting serious.
