I think that a hog that never displays must have had a lobotomy! How boring!
Hognoses need no "taming", I can't imagine trying to get rid of their most basic anti-predator behavior. That would defy their main appeal. And I don't see how it affects handling at all, especially when they NEVER bite.
Besides, hogs rarely play dead in captivity.
So feel free to grab any ol' hog, I am sure it would perk up your male!
