If you are going to have a single baby, think about forming a baby llama play group. Contact other breeders that are going to have single babies. Make arrangements to board your female and baby at their farm for a month or two and then move both mothers and babies to your place for two months. The hassle is well worth it and you will both benefit from the enjoyment of watching the babies play together. I prefer to think of myself as the teacher rather than the boss.
Many trainers use the word dominance to describe how to behave around an animal.
The issue of dominance is a tricky one. Humans come into an animal's life as being entirely different from them and very powerful and omnipotent. We control everything about an llama's environment. I don't think it is a good idea to participate in dominance contests with animals. Assume you are in charge, don't feel like you have to prove it and by all means don't give away your place of preeminence by encouraging animals to behave disrespectfully towards you.
