Finnish Lapphund dogs were used for herding reindeer.

The answer is true because Finnish Lapphund dogs have historically been used for herding reindeer. The breed originated in Lapland, which is an Arctic region in Finland and neighboring countries. The local Sami people have long relied on reindeer herding as a means of livelihood, and the Finnish Lapphund was developed to assist them in herding and guarding the reindeer. These dogs are known for their herding instincts, agility, and ability to withstand harsh weather conditions, making them well-suited for the demanding task of reindeer herding.
