While checking Rolling Dog Ranch's site, I learned of this post, which mentions and gives a link to some photos taken by one of the photographers at the Best Friends Animal Society, Sarah Ause.
Take a look. There are great shots of the animals at Rolling Dog Ranch (in Beautiful Montana), which really show the contentment they feel at being in a place where they are loved. The pictures are truly beautiful.
When I poked around at the photographer's site -- http://bestfriends.org/slideshows/index.html, I came across a number of really touching slide shows, the first of which is about puppy mill dogs being rescued and taken all the way to Manhattan for adoption. Those pictures were featured in Best Friends' 25th Anniversary magazine last summer.
