Blair, start contacting local Humane Societies, vets, boarding facilities, etc. to see if they have any ideas. Explain that you HAVE to stay because your husband is in law enforcement and the city is not allowing him to leave. Maybe they know someone who is evacuating who can take your dogs with them - even if they have to be split up between a couple people.
Also, call Humane Societies and dane rescue organizations more inland and see if you can find temp. placement for them with a foster home until the storm passes and they can come back home. You still have time to help get them there and at least they will be safe and you won't have to worry about them.
Good luck. Let me know if you need any help. I'd take them, but we're worried about Rita coming here, too.
