Kangal dogs are the most popular dogs of Turkey due to their strength, intelligence, loyalty, endurance to extreme temperatures and their lack of predatory behavior towards livestock. In this study to provide genetic information about the distinctness of Kangal and Akbash dogs and hence to provide a basis to conserve them separately, 585 base pair of the mitochondrial DNA (mtDNA) control region sequence was analysed in 105 Kangal and 9 Akbash dog samples. All the results indicated that Kangal and Akbash dogs were different from each other. Comparison of the Turkish data with those from other dogs revealed that Kangal dogs harbour a rare haplogroup which is only seen in Scandinavian (36%), Portuguese (20%), Turkish (20%) dogs and only one Spanish dog, but not in Akbash, Middle Eastern, other European, Eastern Asian and Indian dogs. Furthermore, comparison of the Kangal and Akbash dogs with the dogs from different geographic regions indicated that Kangal dogs are genetically closer to Scandinavian and South West Asian dogs whereas Akbash dogs are more similar to European and East Asian dogs, based on the mtDNA control region sequences Today, the sizes of Kangal and especially Akbash populations are decreasing. An urgent program for their conservation is needed. In order to conserve them separately, it must be understood that these two dogs are genetically distinct. That is why, the main purpose of the present study is to provide genetic information about the distinctness of Kangal and Akbash dogs.
