The Jindo temperament is a distinguished, historic and demanding one. This ancient, relatively rare and highly specialized purebred dog is very difficult to train, socialize and maintain — but if you have the patience, resources and background to undertake such a relationship, the rewards will be great.
You absolutely must establish yourself as the alpha when taking on the life-long responsibility of having one of these dogs in the family; failing to do so will render all future attempts to manage this dog basically impossible. Even when under the command of the pack or human alpha, this top-notch-intelligent dog will exhibit a very independent personality. Training your Jindo will be neither easy nor quick, and despite their potential for aggression, these dogs must be handled gently when being trained.
Another Jindo characteristic is that these dogs are hard-wired to hunt, chase down and kill smaller animals. If you have cats, hamsters or any other such pets, you should not get a Jindo. Their loyalty is also significant to a fault: they are fiercely protective of family members. Even with proper socialization, they may well tend to regard strangers with near-aggressive suspicion. Once you have broken the barrier, however, your Jindo will be eager to please, ready to learn new tricks and set for a lifelong relationship.
