Not possible with a simple dpkg command.   Creative use of perl/awk and
/var/lib/dpkg/available can yield the results you are looking for.

I usually do the following:

# apt-get update
# apt-get install foo

This will tell me what other packages are going to be upgraded because of
an upgrade of foo.  Note that the list of packages that are going to be
upgraded != list of packages that depend on the foo.
