Whats special about a Dogo?

I have hunted with both. From what i have seen the Dogo did just fine but when you lead in i could tell that the pit we have was way more aggressive. The Dogo almost seemed timid and thought about how he was going to go about catching the pig. The pit put the smack on the pig end of story. I have heard and read that they are bread to hunt in pack as running catch dogs, but i have come accross quite a few pigs that i wouldent want a bunch of dogs hanging on to for a while. I just like the aggression of the pit, but have seen the Dogo do ok as a help dog.
