I had a dog when I was in college/graduate school so I know from experience that this is a huge committment and it definitely changes your life priorities.
It sounds like you really want to make this work - so you'll have to make some hard choices about your life style. Mostly … have patience, patience, patience.
Don't look at the piddle pads as a long tern solution - I think that's a bad idea. Basenjis can hold their urine for many many hours but the puppy needs to learn this (think human toddler). Basenjis do well on the reward system so reward lavishly when Dexter potties outside but don't get angry when he piddles inside (I was going to say "just suck-it-up" but not literally :D) . If he is using the pads or newspapers, gradually move them to the door and then outside so he learns that is where to go. And when you are home, gradually lengthen the time before you open the door.
It will take some time to have a well-trained potty experience.
