Some assumptions have to be made here, because it's not all clear.

Is there precisely *one* .dpf file per directory?  With unknown name?
And do you want the output file to have the same name, except for the
.dlg suffix?  And it's just a single level of subdirectories, not
fully recursive?

for dir in */; do
  ( cd "$dir" || exit; file=(*.dpf); output=${file%.dpf}.dlg;
    autodock4 -p "$file" -l "$output" )
done
