The dogs in the image above are Turkish lions - native Kangal dogs working to protect a sheep herd that are just out of the frame. These are adolescent pups. (As always, click on an image for a larger view.)
The next two images are of guardian dogs in Mongolia - typical of the dogs we saw in our travels there.
The next three images are Spanish mastiffs, ,working to protect sheep, goat and cattle herds.
Portraits Of Pastoralism, and this crowd-source funding program is doing a funding challenge for us through March 20. If you are interested, have a look at the project page, and be sure to watch the video where you'll see some of the images in the exhibit, as well as a sheep busily picking my pockets as I try to talk seriously about the project.
