In any breed population, genetic diversity is a key factor in ensuring the breed’s health and longevity. This diversity is often maintained through the presence of distinct bloodlines within the breed. A bloodline represents the lineage of a dog, tracing its heritage back through many generations. Each bloodline can carry specific traits, abilities, and sometimes … Read more
Haplotype-based Phylogenetic Classification is an approach to studying the evolutionary relationships among organisms by analyzing the genetic variation in their haplotypes. Haplotypes are sets of closely linked genetic markers, typically single nucleotide polymorphisms (SNPs), found on a single chromosome. They are inherited together and can provide valuable information about an organism’s ancestry, population structure, … Read more
The ethocognitive model of an English Shepherd, or any dog breed for that matter, is a theoretical framework that seeks to understand and explain the cognitive, emotional, and behavioral aspects of a dog’s life. This model is particularly useful for trainers, breeders, and owners who aim to optimize the dog’s well-being and effectiveness in various … Read more

To achieve this level of socialization, the process must begin early and continue throughout the dog’s life. The critical period … Read more
The long-term health and vitality of the English Shepherd breed depend on maintaining genetic diversity and minimizing inbreeding risks. This short article compares two approaches for achieving these objectives: perpetual outcrossing with a cognitive bias towards low Coefficient of Inbreeding (COI) percentages versus bloodline conservation. We discuss the pros and cons of each strategy … Read more
The study of farm dog bloodlines, such as the Black and Tan English Shepherd, often encounters numerous challenges, including vested interests, incomplete records, human stories and myths, genetic diversity, and changing breed standards. This article explores these challenges and discusses various methods employed by researchers to overcome them. By utilizing historical documentation, pedigree analysis, … Read more
In this article, we propose a phenotypic matrix approach to evaluate and select English Shepherd farm dogs for inclusion in conservation programs. A phenotypic matrix allows for the systematic assessment and comparison of different dogs based on a range of traits, such as size, coat type, energy level, trainability, adaptability, temperament, health, and working … Read more
