Netherlands

The Nederlandse Schnauzer Club lists four kennels under middenslagschnauzer, pepper and salt. Its black middenslag line on that page was empty. Towns below are taken from the kennel’s own site where that site states one. Pallouko’s page does not give a town, so the place is the Netherlands, from the club list.

All four names are on the club page: Nederlandse Schnauzer Club, schnauzerfokkers.
