Over the past few years, there has been a significant progress in genetic testing in dogs through the development of genomic maps, which make it possible to determine the background of polygenic genetic diseases. The information obtained by mapping the canine genome, a detailed marker map, and the understanding of genome architecture have changed the possibilities and direction of canine genetic research. It is now possible to understand the genomics of the qualitative and quantitative traits associated with the phenotype, genetic predisposition, and genetic background of canine defects and diseases. Investigations of canine genetic diseases are particularly valuable because their results can be used in human medicine. From the medical point of view, genetic diseases in both humans and dogs are similar, which makes it possible to test new therapeutic approaches in the case of orthologous genes containing mutations responsible for genetic disorders.
