Your real problem lies somewhere else: You lack motivation because your work lacks a long-term perspective. Being a freelancer who sells his personal time is not what you intrinsically aimed for. You need something which is it worth to stay home alone and this is not being a mercenary selling his time for money. And the goal can not be just 'to work from home and being free' either, you goal must be way bigger and 'working from home' is a means to an end.

Once you work on something big structuring the day with all good things like exercise, good food, socializing comes by itself and you won't need a dog or any other mumbo-jumbo, though Pomodoro comes sometimes handy just to get started and getting shit done since some procrastination always happens.

This is my experience from working home for the first years of my company (which was the most productive time of my life).
