Are there any breeds of dogs which do not require a morning walk?

I have athletic commitments very early in the morning, so on weekdays during the school year I cannot walk a dog in the morning. My parents are firm that if we get a dog, I will be fully responsible for taking care of it. They have to get to work in the morning and don't want to have to add a dog walk to their morning routine.

I want to get a dog, but only if I can take care of it properly! I don't want to get a dog which will suffer if it does not take a morning walk.

Thank you for your help!
