## Abstract

Dog breeding practices have evolved in the last century, shifting from an emphasis on functional traits to prioritizing aesthetic considerations as dog shows gained popularity. The formal establishment of kennel clubs marked the rise of breed standards prioritizing physical appearance, which inadvertently led to the proliferation of breeds with health issues stemming from genetic defects. Selective breeding and inbreeding have led to significant health problems, necessitating initiatives to enhance genetic diversity and breeding ethics that prioritize health over appearance. While the practice of crossbreeding, leading to designer breeds like Labradoodles, may offer increased genetic diversity and potentially fewer health issues, purebred dogs, bred to conform to specific written breed standards, provide predictability in terms of traits and are well-established regarding their characteristics and standards. This review emphasizes the importance of rigorous veterinary assessments of morphological traits during breeding soundness examinations, as deviations from breed standards or newly introduced characteristics can negatively impact reproductive health and progeny wellbeing. As dog breeding continues to evolve, the integration of ethical principles and health-focused practices becomes essential for safeguarding the future of canine companions.

This article highlights the importance of evaluating the morphological characteristics of female dogs during breeding soundness examinations (BSEs) to assess their reproductive potential and ensure the health of future offspring. Key traits considered in this evaluation include body type, body condition score, skull size and shape, mammary gland conformation, and coat quality. Each of these factors plays a significant role in the health and fertility of breeding females. For example, deviations from breed standards in body size can lead to complications during pregnancy and whelping, while an inappropriate body condition score may disrupt hormonal balance and reproductive cycles. This review also addresses concerns related to brachycephalic breeds, whose conformation can contribute to respiratory and reproductive issues. Additionally, assessing vertebral and pelvic conformation is crucial to prevent dystocia and other complications during delivery. By systematically evaluating these morphological traits, veterinarians can promote ethical breeding practices that prioritize the welfare and genetic health of both breeding females and their puppies. Therefore, integrating comprehensive morphological evaluations into BSEs is essential for responsible dog breeding management, ultimately supporting better reproductive outcomes and healthier future generations.
