1980 The cartoon I read when I was a child shows a puppy looking for its mother. Who knows its name?

The protagonist Weng Weng is a white puppy with fighting dog blood. In order to train him, the master forcibly separated his mother and son, leaving Xiaobai alone on the long road to find his mother and wandering in a strange world. On the way to find his mother, he met two companions, Yeke and Pantai, who wandered with Xiaobai until Xiaobai found his mother.
