Here is a map to show the proximity of the countries Slovakia and Hungary, and thus possibly the relation the Chuvach and the Kuvasz.
Also the Tatra Mountains in the northern part of Slovakia share a border with Poland, the home of the Polish Tatra Ovarchka, another "cousin" of the Kuvasz.
Hungarian Kuvasz - Slovak Chuvach - Polish Tatra Sheepdog -- all connected geographically, while still in different terrains: mountains, plains, plateaus.
