golden retrievers

I plan to get a dog which is a golden retriever or a labrador. But i live in a small house with no yard. I don't get enough exercise due to school works. I'm having a hard time deciding between the two breeds. should I get another breed? :confused:

I honestly have no clue where to put this post so I am going with the breed section (it's kind part breed question and part new dog question.) We have a lab Pyrenees mix who has bonded with my dad, and no one else in our family. The problem is with my dad's new job, he can no longer take her...
