: When a
puppy is born, the testicles are retained in the abdomen. They usually
descend into the scrotum between four and ten weeks of age. Although
their testicles had not descended at six weeks of age, do not be
distressed. Wait at least until twelve weeks of age to make any
determination of abnormal testicle retention. If the testicles have not
descended by four months of age, the puppy should be castrated, which
may require an abdominal surgery, similar to spaying a female. Retained
abdominal testicles can cause many serious problems if not removed.
