I saw my friend’s pit bull/McNab cross take down a bull.

In what context?

[sport]

In Florida, ranches used to have dogs [pit bulls mostly[ that herded cattle. They were work dogs. They were kept in pens when not working. They would jump up and grab the cow by the nose and flip them. They were not played with. They were not petted. They were called catch dogs.
