As you stated earlier, there is not any (visible) poop in the photo. Also, there aren't any holes--so either the dogs aren't 'diggers' or they haven't been there long. With the possible exception of the fenced in area, it looks as though every dog has his/her own house. The houses don't seem to be in too bad of condition (ie no (visible) holes, no broken boards, etc) Can't tell if the water dishes are filled, though.

It would be interesting to see the musher's lodging at this particular site.
