If your Sheltie has serious ethical/religious issues about eating meat, and is willing to do the research and work necessary to get all the nutrients necessary from a plant-only diet, then a vegan/vegetarian diet is definitely doable! 
Otherwise, unless there is a medical reason, I would feed your dog what s/he was meant to eat - a diet that relies heavily on meat. It is wrong for us to impose our ethics on another species (again, barring medical issues)
