It's Kaylee

I like the name, I think of her with that name and the others, while interesting, just weren't cutting it, so my cute little pup is officially Kaylee, named after Kaylee from the TV show Firefly and the movie Serenity.

edited to add:

And I just got a text from the puppies' current owner, they got to visit the vet today and get their first shots. They are also  6 weeks old today. The puppies are all very healthy. The vet wants them to be 7 pounds next Monday at week 7. My cute little Kaylee weighed in at 8 pounds 12 ounces. I guess the granddaughters are over feeding the kibble. lol
