We have two Mini Schnauzers, Miss Daisy and Perry. Schnauzers are great dogs, they do not shed, they are funny, excellent watch dogs, can be very independent charactors, however they need to be socialized, socialized and socialized. If I was to get a Schnauzer and I had kids, I would get a puppy and let it grow up with the kids, most of the time getting a rescue unless you have older kids, does not work, if they have not been around kids they can get pretty snappy. I have seen Schnauzers that are wonderful with kids and Schnauzers that are not good with kids like our two. Some Schnauzers are good with other dogs and some like ours are not, it depends on whether they have been socialized. We made the mistake of not socializing them enough.
They def. need to go to obedience puppy school.
They do need to be groomed about every six weeks, the grooming is not cheap but then one can do it yourself as we do.
I think it depends on how much time and effort you are willing to put into a Schnauzer that will make the difference. We have had Schnauzers for the last 20 years and love them dearly, once you do have a Schnauzer, you will always have a Schnauzer, lol.
