One thing you need to remember and that is a dog is for life. It is not a toy that you can take into your life and then leave behind when you go to uni. YOu are staying at home at the moment and that could change somewhere along the line. Will your new circumstances have room for a dog.
You are talking about some big strong dogs that will require intensive training on a permanent ongoing basis. Are you in a position to say that without fail, I will go to obedience/agility/flyball etc tonight instead of going out with Mr Handsome over there.
You are also all along talking about the dog YOU want. What input is your mother going to have. After all she is the one who is going to house and look after him whilst you are at school. Has she the strength to control a Rotti, or a GSD , or GSP, or a Staffy?
I too believe, reading between the lines, you are too young to take on the responsiblity of dog ownership. If you really insist on having a dog now, then buy your mother a Maltese or a Silky and help her look after it. Let it be her dog so that when you leave home it will not be "left behind". And don't make the mistake of thinking that just because it is a small white fluffy thing, it cannot do obedience or agility.
On the research side, you do not need a computer. There is a library full of books on dogs. YOu could find out where and when dog clubs in your area meet and go along to see what dogs they have and talk to the owners. Dog people love talking about their dogs.
