It can also be used as a water dog. Mainly bred in Ohio, Kentucky, Virginia, and Tennessee, it has been registered with the United Kennel Club since 1998. The Mountain Cur Breeder's Association was formed in 1957. The Mountain Cur is intelligent, easily trained, and neither vicious nor shy. They are known to try to please their masters. They are not, however, dogs to be trifled with; historically many a cur died fighting to protect their family from attackers or dangerous predators.These curs were bred to work, and if deprived of the opportunity to hunt, guard, or work around a farm they will grow anxious and bored. When they have a job to do, these dogs are generally happy and obedient, and are able to get along well with children and other pets.
