You could try putting "Livestock guardian dogs," in the search box and see what comes up. Sometimes breeders put up ads in the BYC buy,sell, trade forum under the heading "everything else for sale." You could even put up an "wanted to buy Anatolian pup," but, you need 20 posts in order to participate.
You can get the 20 posts quickly, if you greet 19 members, like I am greeting you. You might also try posting on your state thread. Go to "where am I, where are you," in the social forum - locate your state and post there saying you are looking for such a pup for your goats. People serious about raising these dogs, usually get them used to goats, or chickens, or geese etc. as soon as they can walk. They aren't born being perfect livestock dogs, they need to grow into it and be shaped by training and experience. Good luck finding a pup to suit your needs.
