This dog will not house-train?

I know this question has already been addressed several times, but my family has owned this dog for almost a year. She's a west highland terrier. Although she is let outside several times a day, if she does actually "go" out there, it is only a mere coincidence where she just happens to have to go while being outside. Everytime I see her "go" in the house, I rub her nose in it and put her outside, but I'm in college, so I'm not always around, and I'm worried that my family just isn't capable of training her. This dog will be a year old around April/May. Oh yeah, the crate/kennel thing...she has no problem with urinating deficating all over her space, and it's only like 1 ft X 1.5ft, so she's practically laying in it. I figure there's gotta be something wrong with this dog (trainers probably lol) since from what I have heard a dog's kennel is "the only place they'll never do it in."
