Mollie

Mollie is an alternate spelling of Molly, a diminutive of Mary, derived from Hebrew Miryam. The original meaning is debated — possibly 'bitter,' 'beloved,' or 'wished-for child' — but the name itself has long since shed any somber associations and settled into something bright and irreversibly cheerful.

Mollie (with an -ie) has a slightly softer, more old-fashioned charm than the more common Molly spelling, which is exactly why some owners prefer it. It's a name that has been popular for pet dogs for well over a century, sitting comfortably in the sweet spot between classic and warm. A Mollie is the dog who is always happy to see you, always willing to try something new, and completely incapable of holding a grudge. The -ie ending gives it an extra touch of endearment that the -y version doesn't quite replicate.
