Miniature schnauzers will lose some hair as humans do but never shed as most dogs will. The hair they lose will be in your brush when being groomed. They have no dander or dog smell. They need to be professionally groomed either by clippers or by being plucked periodically. Like the poodle the hair must be removed from the inner ear or they can develop a yeast infection. If you have allergies to dogs, this is the one you want. Bathing them periodically is very helpful also. Pollen can collect on their coat while having a fun day outside.
