The issue of inherited disorders in pedigree dogs is not a recent phenomenon and reports of suspected genetic defects associated with breeding practices date back to Charles Darwin's time. In recent years, much information on the array of inherited defects has been assimilated and the true extent of the problem has come to light. Historically, the direction of research funding in the field of canine genetic disease has been largely influenced by the potential transferability of findings to human medicine, economic benefit and importance of dogs for working purposes. More recently, the argument for a more canine welfare-orientated approach has been made, targeting research efforts at the alleviation of the most suffering in the greatest number of animals. A method of welfare risk assessment was initially developed as a means of objectively comparing, and thus setting priorities for, different welfare problems. The method has been applied to inherited disorders in pedigree dogs to investigate which disorders have the greatest welfare impact and which breeds are most affected. Work in this field has identified 396 inherited disorders in the top 50 most popular breeds in the UK. This article discusses how the results of welfare risk assessment for inherited disorders can be used to develop strategies for improving the health and welfare of dogs in the long term. A new risk assessment criterion, the Breed-Disorder Welfare Impact Score (BDWIS), which takes into account the proportion of life affected by a disorder, is introduced. A set of health and welfare goals is proposed and strategies for achieving these goals are highlighted, along with potential rate-determining factors at each step.
pedigree 犬遗传疾病问题由来已久,有关与繁殖实践相关的疑似遗传缺陷的报告可以追溯到查尔斯·达尔文(Charles Darwin)的时代。近年来,人们已经了解到大量有关遗传缺陷的信息,遗传疾病的真实问题也逐渐浮出水面。从历史上看,犬类遗传疾病研究领域的研究资金方向主要受到发现对人类医学的潜在可转移性、经济利益以及犬类工作目的的重要性的影响。最近,人们提出了一种更注重犬类福利的方法,旨在通过减轻大多数动物的最大痛苦来集中研究工作。最初,开发了一种福利风险评估方法,作为客观比较不同福利问题并为其设定优先级的手段。该方法已应用于 pedigree 犬的遗传疾病中,以研究哪些疾病对福利的影响最大,哪些品种受影响最大。该领域的工作确定了英国最受欢迎的 50 个品种中的 396 种遗传性疾病。本文讨论了如何利用遗传疾病福利风险评估的结果来制定长期改善犬健康和福利的策略。引入了一种新的风险评估标准,即品种-疾病福利影响评分(BDWIS),该标准考虑了疾病影响生命的比例。提出了一组健康和福利目标,并突出了实现这些目标的策略,以及每个步骤中的潜在限速因素。
