Care
Coat care and exercise below are only what two kennel-club pages state for the Schnauzer. This page does not add a grooming recipe of its own.

Trimming and coat
The Schnauzer Club of Great Britain, on its routine-grooming page, says regular maintenance matters for whichever size of schnauzer you keep. It recommends a weekly routine: a terrier pad on the body coat, then a slicker and a metal comb through the beard and furnishings, with extra attention where hair knots under the arms and in the groin. The same page says it is worth trimming excess hair from between the pads, and it refers to dogs that are regularly trimmed, with a groomer checking the nails as part of that trim.
The Kennel Club (United Kingdom), on its breed page for the Schnauzer — which it calls the original variety — lists grooming as more than once a week.

Exercise
The Kennel Club lists exercise for the Schnauzer as up to one hour a day. The same page gives the size as medium and the home as a small house, with town or country both suitable.
