Is it unreasonable to think about owning a dog in college?

It seems a bit far-fetched, but after losing my best friend and companion of many years (a very sweet soft coated wheaten, who passed of a heard disease at age 12), I'm itching for another dog. However, I am sadly unable to get one, as my mother doesn't have a good taste for dogs (she is more of a cat person). I have a bit of a fantasy of owning one in college, as living without pets does NOT suit me. Of course, this would not be in a dorm room, maybe an apartment or flat, or maybe even a condo close by. I'm not the type to party late into the night and be out very often, but would getting a puppy a year before college to train him, then taking him with me sound too dream-like to be fair for my new friend? I would prefer a medium to large dog that would be a jogging companion... Would this be an unfair life for the poor dog to be my companion while I'm still in school?
