The excessive urine in dogs after neutering may be caused by a rapid drop in hormone levels or other diseases, such as urinary tract infection, cystitis, bladder stones, etc. It is best to go to the hospital for examination. Generally, this situation occurs more often in female dogs, so after the dog is neutered, special attention should be paid to not letting the dog lick the wound to avoid infection, and do not give the dog food or water within eight hours after the operation.
