The dog oops up to you as her caretaker her serrogate mom, though she lives the others in the family, her heart belongs to you and whenever your gone she mourns your absence and refuses to eat because she's feeling abandoned.
I would talk it over with the family about taking het, it's lungs like she would be the happiest with you, however a lot depends on your ifrstyle. If your going to school full time and eorking then the dog only "sees" you when you go home to study or seep. Not much of a ire for a dog, even if you hire a dog walker to come in once a day. There's no human companionship and nothing to do. Eaving a dog outside a day is a little better but your just changing the location, outside alone 16 hours a day, no human interaction when used to a family. Just pointing out worst case sitution.
If you leave the dog with the family you have to worry if she will be too depressed to eat or play. Though she is looking fed, looked after by the family she will be miserably lonely because your not there. Eventially she will bond with another family member but it will take a little time
Solutions... if your going to be gone a lot and someone's at home at your parents you could eave the dog during the day and pick her up at night.
Next solution. Leave the dog home and go home to visit her, make sure the digest getting enough to eat and is happy. If the dogs miserable you can always take her with you later on if things don't work out at home.
Dogs are highly adaptable and ally don't care where they live, mansion, tent, apartment, home, car... as long as they have their human end can get out and about to exercise.
In my teen years I eats a more or less wanderer. I lived here no there with family, friends bed occasionally went camping on my uncles farm amongst his horses. My dog aleays stayed with me through all my crazy adventures. She loved riding in the car, taking a mere18 hour car ride for the heck if it, or hiking a 30 mile trail for something to do. As long as she was with me she was settled and happy, where we lived did not matter.
Think things through on what's best for the dog, being sithyou sounds like what will make her happiest. You will have to figure out how much sone time the dog will have living with you. Leaving her home you may have to stop by every day for a month or so until the dogs used to your absence or take the dog with you and do the same with visiting the family until the dog adjusts fully to being away from home.
Whatever you choose try and make sure which is less stressful to the dog, whichever you choose just know the dogs happiness is being with people that love her
