What does Breathing like a picadored bull mean in figurative language?

A picadored bull is a bull that had its neck muscles lanced as part of a bullfight (to keep its head lowered), which further enrages the bull. A person (often more than one) who lances the bull is called a picador. After it is lanced and gets angrier, it is called a picadored bull.

So metaphorically, this would be heavy breathing, coming in ragged snorts.
