The main carriers of the Bubonic Plague were fleas and rats. The fleas got it from the rats when they bit them. When the rats died, the fleas went to new hosts, bit them, and gave them plague in the process. Usually the new host was another rat, because rats hang together, but sometimes there was no rat to go to, and the fleas went to whatever animal they found.
