How to have Regular expression keep first 14 characters and start changes at character 15 or beyond

I need a regular expression that keeps the first 14 characters of a string intact with no changes.  However, if there is a hypen in character 15 or beyond, remove the hypen and all text past the hypen.  If the string is 14 characters or less, do nothing.
Any help on this is greatly appreciated.

just get the first group of this regular expression:

/(\d{14})(\-.*)?/

This will only keep the first 14 characters if there is a hyphen beyond that point.
s/^(.{14}).*-.*$/$1/

This will keep the first 14 characters and anything up to but not including the hyphen.
s/^(.{14}.*?)-.*$/$1/
