What breeds of dogs are more low maintenance?

Are you sure it has to be pup? Puppies will be high maintenance for the first 6 months or so. Would you consider and older pup (6 months to a year old) or an adult? Training a pup is way more work than most people imagine before they get one. You really don't say if you are gone all day or not. I'm not sure I would do the pup thin if you cannot be home most of the day. Some dogs are a lot more people dependent than others, but most adult dogs should be able to tolerate being alon for a few hours a day. Some other question you might want to ask is: how high energy is this bred and how much time will you be able to devote to walks and playing with him? A lab is a great family dog if you are able to provide a decent sized fenced yard and some long walks. A shih tzu might be more adapted to a couple of of short walks or just playing in the yard. Also consider shedding and grooming. Now, if this is a concern, you can google low shed breeds- you might be surprised to learn a lot of long coated breeds are low shed. I have a golden retriever/beagle mix who is a moderate shedder but requires no more grooming that an occasional brushing. I alos have long haired shih tzu/maltese mix who is brushed daily and requires the occasional clipping but does not shed visibly in the house at all. I would highly recommend this mix. He is about a 10 pound adult, outgoing, likes absolutely everyone including tiny kids and cats and is not too high energy. Loves to play fetch with toys and stuff and will go on a 15-20 minute walk if you are willing to take him but is not hyper or barky and lays around a lot when no one is playing with him. He is sleeping under my computer now with his chin on my feet. He loves company but does not have problems being left alone for a few hours.
