The most powerful dog in the world is the golden retriever. There is a poem on the Internet that says, "A golden retriever overwhelms a German shepherd, a golden retriever kills a Rottweiler Nebit, a golden retriever kills a Tibetan mastiff, three golden retrievers sink an aircraft carrier, and four golden retrievers dominate the universe." A new female college keeper thought Simba was a lion cub and imprisoned Simba in the lion park. From then on, Simba started to have a peak life.
