All of the breeds I'm looking at are double coated, but their coat isn't long. I've looked at Anatolians and Kangals, but there seem to be no breeders of those here. The other two I'm looking at (and have already located breeders) is the Molossus of Epirus, and the Central Asian Shepherd. I'm a little bit hesitant on the latter, since I've heard/read a few bad stories. That said, I haven't interacted with one in real life
I won't be getting an LGD for quite some time, so I do have time to make a good choice
