As a behaviorist I am often asked how to eliminate aggression once it has surfaced. My advice is always to first rule out a medical cause and then seek out the advice of a knowledgeable behaviorist. Seeking the help of a trainer without the knowledge or experience in behavior modification can be very dangerous and prolong the treatment process.
Dog aggression is a complex behavioral issue and just as people have different learning styles so does your dog. Aggression can be caused by a genetic, environmental, or psychological cause and can appear at any time. In most cases if left untreated aggression will normally escalate without professional help.
