This time is uncertain. It depends on the care of the parents and the recovery of the wound. However, under normal circumstances, the swelling will subside in a day or two. If your dog’s balls have not been there for three or four days, It's best to take the swelling to the hospital for treatment. After the dog is neutered, parents should follow the doctor's instructions to clean and disinfect the dog's wounds every day to avoid infection.

Tip:

A dog in heat will not only affect the parents’ life but also increase the probability of getting sick. It is best for parents to neuter the dog as soon as possible.
