EVALUATION OF THE MORPHOLOGICAL CHARACTERISTICS OF TOBET DOG HAIR

Abstract

Modern cynology actively studies the breed characteristics of dogs to preserve genetic diversity and maintain breed health. One of the promising approaches involves the use of hair as a minimally invasive source of information, capable of determining the species or even the breed of a mammal through the analysis of primary microstructural features of hair. Hair serves as a valuable yet simple model object for both fundamental and applied research. This study focuses on identifying unique structural features of the hair in the Tobet dog breed, which can be applied for breed identification and breeding works, as well as for developing scientifically grounded approaches to preserving genetic diversity and ensuring breed health. Our research revealed that Tobet hair is characterized by a single-layered, fragmented medulla with serrated cell edges, an intermediate cuticle position featuring a "regular wave" pattern, and closely spaced scales. The findings highlight the potential of utilizing the morphological characteristics of hair as a breed-specific marker, facilitating ethical research on rare and protected breeds, which is particularly significant for the breeding and conservation of this unique national breed.
