I think a lot of the larger sheep ranchers still use LGDs but some have gravitated towards donkeys, llamas and such. Don't have to keep different food in the fields for these types of guardians. I like the fact that my dogs keep my animals safe from predators and that they also are very well-socialized with humans. Although, the phone repair guys were very nervous the other day because my Lab/BC mix dog was standing quietly at alert, head down and giving them the hairy eyeball for coming in the yard! Good dog!
