The case of a boy in the Oedipal phase is described. After undergoing an eye operation at age four years, three months, he blamed his mother and withdrew his love from her. He regressed to an angry, clinging child, and turned to his female dog as his Oedipal love object. In treatment he acted out his fury at his mother. When this was worked through, he gave up the dog as an Oedipal substitute and returned to his Oedipal relationships with his parents. One and a half years after beginning treatment he was enthusiastically forging into latency. A year later he experienced a sharp, though temporary, regression into the dog-wife relationship after viewing parental love-making. This was followed some months later by another very short regression into the dog-wife relationship, although latency features were apparent at that time. This last regression into the dog-wife relationship was not acted out; it was merely fantasized in our sessions, and the child remained his happy ebullient self.
