This an interesting article discussing the use and benefits of transhumance in modern times. LGDs are not mentioned in this particular article, but LGDs are used in Europe for this purpose today.
This article from France focuses on cattle, but includes sheep and goats:
bovine in the Massif Central, northern Alps and Pyrénées, ovine in the southern Alps, Provence, Pyrénées and Cevenne, goats in Corse and horses in the Pyrénées.
There are nearly 2 million transhumant cattle. In the Provence-Alpes-Côte-d’Azur region, approximately 600,000 cattle spend every summer in the mountain and 100,000 spend the winter in the plains.

How transhumance benefits the environment and biodiversity:
Maintain biodiversity and opened landscapes:
Herds are essential to maintaining open environments. Transhumant breeding is a paragon for environmental protection and natural space improvement: fire fighting contribution, the steppe ecosystem, enhancement of farming fallow land, and maintenance of alpine areas. Since the nineties, breeders have pioneered the various schemes of the Agri-Environmental measures that have continuously succeeded one another.
About the family of Livestock Guardian Dogs...
“To this day flocks are guarded in the hills of Asia, Europe and Africa* by powerful, robust dogs that are neither clumsy nor pacific. Despite the distances that separate them these breeds have much in common, and the Kuvasz is a member of this extended sheepdog family.”
