Maybe whoever thought Chocolate or Black Labs don't shed as much was wearing dark clothing when they met one!

Bostons are pretty small - how old are the children the dog would be around? Shelties do shed, I can attest to that, though they do need to be brushed aften, so that tends to cut down on the loose fur more than a Lab. With any dog, you need to be careful, look at the pup's parents, and see how THEY react with children, whether they are skittish or shy. As someone else mentioned, most non-shedding dogs do need to be groomed, so that is a consideration, too!
