Cryptorchidism
Cryptorchidism is the failure of one or both of the testicles
to descend into the scrotum. Normal descent is often
complete by 6 to 8 weeks of age but may be delayed to as
late as 6 months of age. The undescended testicle may be
found within the abdominal cavity, in the inguinal canal or
under the skin next to the penis. The condition is considered
hereditary in most breeds. There is not complete agreement
on the mode of inheritance. Because of the increased incidence
of cancer in retained testicles, cryptorchid dogs should always
be neutered. A neutered cryptorchid dog should have no other
expected health risks due to this condition

I just found this information. Max's testies have not come down. He'll be 6 months the end of this month.
Has this happened to anyone else that owns a male?
Should I let the breeder know this?
