multiple apostorphes

[Unregistered]

I need help with this following sentence: Mr. K's dogs' babies' grandchildren had birthdays.
Is this where the apostrophes go?

What a very peculiar sentence!

But yes, the apostrophes are in the right places.

[Ronjohn]

It is not necessarily right, unfortunately. The sentence presupposes that there is more than one dog belonging to Mr K that has had "babies". We won't go into the fact dogs have puppies, not babies, however, if there was only one "matriarchal" dog then the apostrophe should be between the g and the s ie dog's. This is the way an apostrophe signifies singular and plural.

Hope that helps a little.
