IMHO, an inguinal hernia is more to be concerned about than a naval
hernia. A naval hernia can wait until the puppy is old enough to
spay to have the repair done. An inguinal hernia, on the other hand,
needs more immediate attention.
An inguinal hernia should be surgically be repaired just as soon as
your vet feels the pup is safe to have the surgery done.
Meanwhile,
"As a note, umbilical hernias in puppies are a genetic or congenital
defect in over 90% of the cases. The disorder is passed from
generation to generation just like the color of the coat or the
animal's overall size. Very, very rarely are they caused by trauma or
excessive pressures during whelping. Animals that have a hernia or
had a surgical repair of a hernia should never be used for breeding.
Additionally, those adults that produce puppies with this condition
should not be bred again." That is a quote from this Web Site

Besides it being genetic, there is also a fair chance that an
inguinal hernia could eventually become strangulated. Then, your
pup's life would be at stake.
