There are many breeds of
livestock guardian dogs (job function). The more common breeds (or crosses) in use in the US are: Great Pyrenees, Maremma Sheepdog, Akbash, Anatolian Shepherd, Kuvasz, Kangal, and Spanish Mastiff. Of these Great Pyrenees, Maremma Sheepdog, Akbash, and Kuvasz are all white with varying coat lengths by breed with the Great Pyrenees having the most and Akbash having the least. There are also personality differences between the breeds in terms of friendliness to strangers; we want our LGD to alert (stay between sheep and bark and/or growl) to strangers but not aggressive towards (charge) strangers. Producers with rustling problems would want aggression towards strangers.
Sam is a Maremma Sheepdog having less coat than a Great Pyrenees, not as broad a head, and not the loose jowls Great Pyrenees can have.
Many working LGDs are crosses of these breeds.
Our next LDG will likely be an Anatolian Shepherd or Akbash for the short coat; Sam's coat gets matted during the winter and keeping him brushed out is not feasible.
