Now that I've picked my jaw up off the floor after reading your post I'll make an attempt to tell you why owning a Rottweiler is a bad idea (for you).
I have a 22 month old Rottweiler who can be the sweetest dog in the world. However, to get her this way she has been in obedience classes since 4 months old, she has been socialized beyond belief since she came home to me (8 weeks) and she lives in a very stable loving home. Having said that, I also own a dog who in the flip of a switch will protect her family, her home, and her property if needed.
Socialization and obedience are a MUST (not optional) with this breed. As mentioned before if you can't handle a Schnauzer, a Rottweiler will run over you, and be miles ahead of you before you can blink an eye. They need an environment that can provide them consistency. If you are a student how you plan to provide this?
I'm going to assume that you are planning to get a puppy from a backyard breeder since you will have a very hard time finding a GOOD breeder to sell you a Rottweiler pup while living in an apartment. Hell, you'll have a hard time getting someone to sell you one if you are honest with them (can't control your small dog, have no past experience with a guardian breed, etc). If you choose to go the backyard breeder route, you can multiple any problems you might think you'd have by 10, even more so if they do not have a correct temperament.
Shedding...Rottweilers shed...TONS. If you don't consider black dog hair an added touch to your wardrobe then a Rottweiler isn't for you. She eats a raw diet as well, so the shedding isn't because of bad food, etc. BTW, I live in Oklahoma and it's very similar to Texas weather wise.
Rottweiler are not a lazy breed. They love nothing more than to work -- they need a job, or they get destructive. They don't require tons of exercise, but a decent amount and if they don't get it they CAN be hard to live with.
It's people like you who give my breed a bad name. People who go out and buy a dog because it's pretty, or because they want to scare the neighbors. I work everyday to bring a positive light to my breed, and make people see them for what they are/can be when properly trained, etc.
