So, you don't need to take care of it when it gets sick, bathe it, take care of its teeth, clean its fur, make sure it doesn't bite your wires or other crucial parts of the house, you don't need to take care of its belongs (bed, toys etc?)
Dogs need care, health and most dogs need to be social as well. You're trying to simply something you've most likely never done in your entire life, which is laughable.
If you want a dog, and want to do it properly, you have to TRAIN IT. This means that you need to be the pack leader. You need to always have treats ready for when it does something correctly, exercise it regularly (running) and always make sure it has FRESH water and healthy food.
It ain't something you can just shrug off, unless you're a fucking moron who shouldn't have a dog in the first place.
