Okay I found an Internet quote that says if the world would be a better place if people tell what they really wanted, so here it is:
I want my dragon to be sheared by diamond shears, not ordinary shears, It doesn't need to behave like the one in sheep's where you sheared it once and wait another time to be sheared again, I just want it to be sheared and get it's dropItems, which is already set per breed, but shearing it damages the dragon by 1 simulating it was painful removing it,
