Re: Puppy plural? (if not young dogs, but Puppy linux distro's)
Actually the correct one is the first one (puppies), and pups would be the plural of pup. When the proper name is used, it should be capitalized: Puppy Linux, Puppy version, Puppy derivative, Puppy install. Talking about a random Puppy version or derivative, puppy or pup (no capitals) would be the correct form in informal terms: a puppy, many puppies, a pup, a few pups.
