Lorenz/Nancy Thelen

Lorenz/Nancy Thelen breed border collies in Atoka, OK, serving Southeastern Oklahoma near Tulsa. With over a decade of combined experience, they are members of regional kennel clubs and follow American Kennel Club guidelines, conducting health screening for hips, elbows, and eyes. Puppies are raised in a family environment, living indoors with daily access to secure outdoor runs and pasture for exploration.

Their breeding philosophy balances working ability with a stable temperament suited for family life and field work. Their program emphasizes the breed’s natural herding instincts and begins early training for agility and obedience. Each litter is limited in size to ensure individual attention and support social development. All puppies come with vet-verified health records and a starter kit detailing nutrition and basic training. Several litters have gone on to work as therapy companions or excel in local trial rings, reflecting the breeders’ commitment to sound temperament and working ability.
