I'm one of the few people in America that's familiar with a 1977 film of the same name http://www.imdb.com/title/tt0076516/ (The Pack AKA The Long Dark Night)and a similar plot device. That movie starring Joe Don Baker was based on the novel The Pack by David Fisher.
I love that movie for what it is (proto-Cujo). Very familiar with it.
This 2015 film does use the core element of people isolated in a house trapped by wild dogs, but there's no backstory or even an explanation as to why the pack exists. I don't think it's a true remake. I'm about 3/4 through it and it's competently made and a little tense, but there's zero investment in either its human or non-human characters, as opposed to the 1977 film.
