Female dogs can drink water about 6 to 8 hours after sterilization, and male dogs can drink water 24 hours after sterilization. Male dogs can drink water later than female dogs because drinking water can easily cause urinary tract infections. After the dog is neutered, special attention should be paid to not bathing the dog or letting the dog lick the wound, otherwise it will easily cause wound infection and affect healing. It is best to wear an Elizabethan collar on the dog.
