Good Lord, another two people who understand the correct use of the apostrophe. I am reminded of the story of a lecturer at my old university (possibly apocryphal) who awarded a student an A+ for his answer to an exam question, which was acceptable, though not exactly brilliant. When asked to justify his marking at a moderation meeting he said, "Because he is the first student in the past 10 years to use a semi-colon correctly in a sentence".
God forbid that I should ever go down the road of grammatical pedantry but I don't think that a dash is quite the same thing as a hyphen, hence my use of the term.
I like dashes - when they're used properly, that is! Also quite keen on a line of dots..... I think both give a more friendly - not necessarily informal - tone to a sentence.
Now I'll sit back and wait for you all to pull my punctuation to pieces.
BTW I believe there is an Apostrophe Society.
My only criticism of your punctuation is that you have typed 5 dots, whereas a line of dots, indicating something left unsaid, should consist of 3, and only 3, dots.
It could be puppy's if the writer was thinking of puppies in general, all puppies of all bitches, rather than just this litter or this group of puppies: 'The puppy's development is exemplified by this litter' ! Then the article could be correctly headed 'The puppy's development'
Now that's something I've never heard before, Mike 11111 (or should it be Mike111?). Is that official? Could you point me to a reliable source to verify? (Not that I doubt you, but I'd like to have chapter and verse to show friends and colleagues).
