Maybe you have to look at it from your parents side. Are they financally stable? Puppy have to visit the vet quiet often for puppy shots which are quite costly. Who will stay with the pup while you are at school/work?

I defonatly would not just go out and bring a pup home. Besides I do not think a respectable breeder will let a young indevidual buy a pup without a parents conscent.

You must think about all of the consequences.
