I did not find this dog but received the following info via email. Thought I'd post here in case some one lost their dog on or near Moab recently.
Found just below the Dewey Bridge Saturday night, August 13, 2011 on an isolated ledge on river right about 5 minutes downstream of the campground put-in just below Dewey Bridge. Was not wearing a lifejacket or collar. Is female and all black, aside from white area on chest and white spot on tip of tail. Appears to be comfortable with rafts, well trained and well fed.
For more information, please call: 435-259-7691. This seems like a great dog. Please help it get home!
