Attend llama conventions and talk to different breeders, trainers, packers and wool spinners. Buy from honest breeders who are ready to give you helpful advice. Know, or at least feel comfortable about, the people you are dealing with. Like in any other business, there are some wheeler dealers. Finally, try to find a good, interested veterinarian.
Llamas are hardy animals that are generally disease-free and resistant.
We still have yet to see a sick llama at our place after 14 years in the business. However, like any other farm animal, they may get sick and require veterinary assistance. Specific preventive inoculations against enterotoxemia and parasites, and occasional deworming can insure a llama's good health. Tetanus and vitamins A, D and E can also be added to the vaccination program. The care and maintenance of llamas is quite easy when compared with other farm animals.
