As purveyors of cute animal videos, we've certainly seen our share of adorable pugs. But this litter of rare white pug puppies, who are seen here frolicking on a couch, are unique even to us.

As fans of the breed know, pugs come in several colors, including fawn, silver/grey, brindle and black. But there are also rare white pugs, who get their color from selective breeding.

Believe it or not, there's some controversy over this variety of pug. Since breeders mix pugs with other dog breeds in order to get their distinctive white color, some argue that they don't qualify as pugs at all.

But whether these cute pups are the result of mixed breeding or a genetic mutation, they're still pretty cute. And that's good enough for us.
