I've heard about that as well, you can get certain breeds of dogs that don't shed hair like the shih tzu. Indeed it will be, but I would like to use my extra energy and it might make me tired a bit earlier at night too. At home for the most part, used to exercise but became lazy. Going to play golf more often as well, you would be surprised at how much walking you do there. I don't think diets really work with people anyway, if someone changes what they eat completely it will never last unless they are extremely determined. I've lost quite a bit of weight in the past simply by cutting down. But I will be exercising just for health reasons this time, not to lose weight as I'm already a healthy weight.
