In the last years, there has been a lot of genetic studies reguarding the dog: there are currently 46 international laboratories are committed to 'Canine Genome Mapping Project' and more and more applications from these studies.

 The project of mapping the canine genome is largely based on using microsatellites (specific points of DNA) for the saturation of the map and identification of markers to be correlated with genes, mainly used for individual profiling and parentage certification.

In the dog is now possible to obtain a low-resolution map, based on genetic markers that still allow a linkage study, like the correlation between genetic markers and genes that are involved in certain phenotypic expressions.

In veterinary medicine the possible fields of application of molecular biology are varied and numerous and it is unquestionably an important role in the breeding and selection of canine bloodlines, not only by genetic control of kinship and identification of false genealogies, but allowing different possibilities. Infact a special emphasis is given to the study of genetic variability and inbreeding, inheritance pathological identification of allelic variants responsible for particular phenotypes (morpho-functional) that can interest the selection of a particular breed.

With the application ENCI guidelines, it will be compulsory to store biological samples for identification through microsatellites of all those who partecipate in the beauty or work championship and for every sire or dam in stud in Italy
