The crazy llama dives low and leaps up very suddenly, catching you in the chin. So you keep chasing that elusive head around until you snare the nose and clip the quick release buckle before your animal student can break away. It appears as if you will become expert at holding a llama or alpaca, chasing a head around, getting hit on the chin and snapping a halter really fast. Based on my years of camelid observation, animals become better skilled at fighting and avoiding the human. I have met llamas and alpacas that were so effective at escape and evasion they could join the Marines.
Humans learn how to put on halters.
This explains why so many new buyers think the seller has misrepresented an animal's training level because they can't halter the llama or alpaca as easily as the seller. You and your animal student will only perfect a skill if you are practicing what you want to do-not what you don't want to do. Practice makes permanent. Be careful what you practice. I suggest that what you really want to practice is putting a halter on a relaxed animal that is standing quietly.
