Hello,
A new dog sounds great, but don't you think the money should maybe go towards a college education or something along those lines. You have your whole life to find your dream dog, but don't waste your chances at getting a good education, job and your own place to live. Then when your are settled and making tons of money from your great job, you can pick out a great rotti or whatever you want. I dunno I guess its your money and is up to you just wanted to give you some advice.
