Although alpacas are docile and social, their primary reaction to everything in their environment stems from their existence as prey animals. In general, they are wary of humans.
They do not like to be grabbed, and there are areas of the body (feet, lower legs, and abdomen) where they do not like to be touched. If handled well, they will interact peacefully with humans, but they won’t come when they are called like dogs or cats, nor do they really like much in the way of petting. Some individuals are however, more affectionate than others.
