MENDEZ, S. et al. Characterization of the Cantabric Water Dog. Arch. zootec. [online]. 2011, vol.60, n.231, pp.405-408. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922011000300022.

The canine breed Perro de Agua del Cantábrico is an ancestral population which probably share a common origin with the Barbet breed, and was used in fishing activities. Morphological traits in this breed are different from those in the Perro de Agua Español. We used the information provided by 21 microsatellite markers on 21 random individuals belonging to the Perro de Agua del Cantábrico and on 108 individuals belonging to other close related breeds (Perro de Agua Español, Portugues, Romagnol, Barbet and Caniche). Genetic diversity parameters and Wrigth statistics were calculated, and population structure on the basis of multilocus genotypes was investigated. A clear genetic differentiation of the Perro de Agua del Cantábrico breed from the rest of the breeds was detected (average F_ST was 0.13). The reproductive isolation of this population has had other genetic consequences as the great genetic homogeneity without the existence of a sub-population structure.
