A yellow pustule on your dog's belly may be caused by bacterial infection. If the situation is not serious, you can apply antibiotic ointment to the dog and observe it for a few days. If it does not improve or the situation is more serious, it is best to take the dog to the hospital. The pet hospital will conduct an examination and confirm the cause before carrying out targeted treatment to avoid delaying the condition.
Tips:
Usually pay attention to the hygiene of your dog, bathe and deworm them regularly, and do not let your dog stay in humid places.
