What is the correct possessive for nouns ending in s?
Me and a friend are wondering whether the right form of the possessive for the plural of a word (say dog) would be dogs' or dogs's
Example sentence:
Those dogs' water bowls are empty
or
Those dogs's water bowls are empty
Also, could you please clear up the use of the possessive on words both singular and plural which end with the letter 's'?
