It appears I took too long editing my thread-start post on the same story...

Seeing-eye dogs also have a fairly strong legal status. People running evac or shelters have to realize those dogs get to come along and it's not their choice.

Probably the main things to shelters & evac to realize is that the handicapped may need a little more room for wheelchairs & such, and that stairs won't work for some. FEMA trailers don't make sense without a ramp.
