I know you are referring to angora fur, but I ran across this theory of why the early dogs may have been selectively bred for their white fur.

**White wool was favoured in Roman times and consequently dogs were selected for white colour, leading to breeds such as the Kuvasz and Pyrenean Mountain Dog, typically of 35-65 kg (de la Cruz 1995). Lucius Junius Moderatus Columella in res Rustica (65 CE) and Macius Terentius Varro in Res rusticae (36 BCE) wrote that white dogs were preferred as they could be distinguished from wolves and other predators; modern authors have suggested that coloured dogs pre-dated the ability to wash white wool and dye it in various colours. There is evidence, though, that livestock themselves may have been at least partially involved in selecting the dogs that guarded them, as they were seen to be more comfortable with the dogs that most resembled them in appearance (reviewed in Taylor 2000).**

I watched a really interesting program one time on training guard dogs for sheep...as soon as the pup is weaned, its put in with a mother sheep and her lambs...he grows up thinking he's a sheep and will take on wolves if necessary...good program..those dogs are awesome...Great P. are gentle when around the house, but not in pasture with sheep or goats...Our friend that has the one that got shot had a jack russell terrier that thought human legs were something to chew on...Nasty little critter. He had a name the woman said but only answered to shithead...LOL
