I learned about the importance of the timing, not just for delivering the click, but also for delivering the reward. With our llamas, we were pretty laid back about when we delivered the rewards. We are getting much better.
The course also reinforced my understanding of the need to set the criteria in advance, so we know exactly what we are looking for. A llama is a big animal and can be moving over quite an area, which can confuse the reinforcement process if we don't set exact criteria in advance. We have the tendency to be training more than one criterion at a time, which confuses the animal.

Llamas, being large, also can tend to move slowly if they aren't really into the training process. They can move fast, but more frequently will lag.
Increasing the rate of reinforcement keeps their interest a lot more than letting them just get reinforced whenever.....

And the most important thing is the shorter sessions. Our tendency had been to train until the llama wouldn't move at all any more. The 5 to 15 minute sessions are much better.

Basically, training llamas is not much different than training any other animal. There are lots of things that they can do. We have 8 children in our 4-H club that train llamas to halter, lead, carry a pack, go over obstacles which include stairs, ramps, bridges, jumps, accept petting from strangers (one of the harder things), picking up feet, accepting grooming, looking in
their mouths (not too easy either), and pulling a cart. For children, clicker training works with handling llamas that the children obviously
could not out-power. It also creates a much more positive interaction. The llamas actually come up and ask if it is their turn to be trained.
