I am in the process of updating this webpage so please be patient.  Every Schnauzer owner has an idea of how they wsnt their dogs to be groomed.  A lot has to do with their hair type and how easy it is to maintain.  It also has to do with the owner and how much time they want to put into grooming their pet.  If you do not brush daily or at least a few times a week, do not expect them to look good and knot free. If you have a mega coated Schnauzer, you need to invest in grooming sessions every 2-4 weeks, super coats every 3-5 weeks, and standard coats can go at least 4-6 weeks.  This is of course, as long as you are taking care of them in between.  Otherwise, shave them down and don't complain.
