gsicard i saw that documentary . Designer Dogs . Caucasion Ovcharka is very loyal to his family members but will not hesitate to strike if he see any danger . Ovcharka indeed one of the bravest dog i have ever seen . Its in Ovcharka blood , they doesnt need no training for protection . They are one of the finest guard dogs you can find in today's world . There are many variation of Ovcharka . If you go to North Pakistan and Afghanistan you will Ovcharka type dog called Koochees or Palegies . These dogs in Afghanistan are often used in dogFighting . Now this is tricky . Im sorry for what im gonna right ..plz forgive me . but i think its my duty to give info about this dog . lot of times these dogs compete against local dogs (bull-breeds ) . For this dog lot of people only use bear-fighting dogs because for one reason . bear-fighting dogs are trained to fight against bears and they only attack on bear nose . because this is the only part of bear which doesnt have thick skin . i have seen koochees in Quetta beating gull terriers , even sindhi bully kutta because of one thing . Koochees ( all the ovcharka type dogs ) contains to thick skin with heavy hairy coat . it gives them full of protection when they are fighting with other dogs . Thats why in Pakistan when-ever there is koochee fight against Gull Terriers or any other bull-breed first they trained their gull terrs etc and often they use bear-baiter gull terrs or bully kutta's . Bear fighting dogs are the only dogs i have seen beating Ovcharkas because they only attack on koochees nose . Otherwise if you put any non-nose trained fighting dog against koochees or ovcharka that dog is in big big trouble . You may found Mix results . Overall i really like Ovcharka's .
