There is emerging interest in linking vitamin D status to physiological health and disease states in the dog, as evidenced by the recent increase in publications in this area. This research has most likely been spurred by the studies exploring vitamin D and disease in humans. However, there are important differences in vitamin D intake and metabolism between humans and dogs that should be accounted for. The understanding of basic vitamin D metabolism and the relationship between vitamin D intake and vitamin D status in dogs remains even more limited than current knowledge in humans. This review will summarize current knowledge of vitamin D in the dog, including metabolism and dietary recommendations. Emphasis is placed on the limitations to current knowledge. Studies investigating links between vitamin D and disease will be discussed in light of this knowledge. Suggestions for future research, including the development of reference ranges to define blood vitamin D sufficiency, are provided.

将维生素D状况与狗的生理健康和疾病状况联系起来的兴趣日益浓厚，这一领域最近出版物的增加证明了这一点。探索人类维生素D和疾病的研究最有可能推动了这项研究。但是，应解释人与狗之间维生素D摄入量和新陈代谢的重要差异。对狗的基本维生素D代谢以及维生素D摄入量与维生素D状态之间关系的了解仍然比人类目前的知识更为有限。这篇综述将总结狗中维生素D的当前知识，包括新陈代谢和饮食建议。重点放在对当前知识的限制上。根据这种知识，将讨论研究维生素D与疾病之间联系的研究。提供了用于未来研究的建议，包括制定定义血液维生素D充足性的参考范围。
