The "stand" posts reminded me of another "adjustment" in the OB classes. The hunting/field command for that expectation is actually "whoa". In one of my regular OB training routines all my retrievers are expected to return to heel from a distance doing "here" spaced with alternating "sit", "whoa", "down" commands and/or remote drops. It is an excellent responsiveness drill.
As was mentioned "whoa" is very useful at the vets (standing examinations & taking temperatures) and for grooming. I know "whoa" makes "Dremeling" my dogs' hind paws easier and when doing the mandatory bitch checks at HRC hunt tests, too.
And "whoa" is a given if you are working with pointing Labs.
One thing I carefully avoided at the classes was mentioning anything about a heeling stick or e-collar.
