Why pure South American bloodline llamas?

South American import line llamas often have the small size
and wonderful, easy-going dispositions we like.

In South America, the native Quechua and Aymara
native peoples of the Andes generally raise llamas
very "hands on", they use very little fencing and no
halters. So the animals are more tractable due to
frequent handling.

Why Miniature Llamas?

Miniature llamas are cuter and eat less.
Small llamas take up less barn and pasture space.
They're more huggable for most of us and they
won't outgrow the children.
The non-llama owning public is less intimidated by
small llamas and people who don't feel up to the
challenge of owning standard-sized llamas may be
drawn to minis.

Often "North American" llamas are larger animals,
approximately 43-45 inch ranged measured at the withers. 
South American llamas, often are about 38-40 inches or less. 
The AMLA considers miniature llamas to be "3 years of age
or older that measure no more than 38 inches at the withers
(front shoulder).  Foundation Stock Miniature llamas are
breeding llamas that "exceed the 38-inch height standard
for miniatures by no more than 2 inches or 40-inches
maximum height."
