I know it is not your fault, so luckily my wrath is not aimed at yourself as you are just a concerned friend. :-)
The only advice I can give you is if I were a friend of this person I would be calling the rescue, the dog needs re-homing, it's needs are not being met at all. :-(
Why on earth did this person get a dog? A rescue dog at that which has lost it's previous owner, and is feeling unsure and needing attention just like a puppy would coming into a new home.
The husband does not like the dog............ great

poor thing, not off to a good start is it? :-(
Your friend works 8.30-5pm, with 45 mins travelling time, in the morning your friend will be getting ready for work herself, having breakfast/shower/any early morning housework? Where does the dog get attention then?
Then when back from work between 5-6pm, it will be dinner/housework, attention to hubby and other social activities, a walk is probably the only time the dog gets to have any fun. I suppose your friend thinks a dog being in the same room is socialising with it.
Then she is off to bed and the dog is whining, I'd whine too, it has only had a few hours of someone being in the same house and it knows when she gets up in the morning it will be alone again, and not be getting enough exercise or time given to it.
The only question being asked is how to stop the dog whining, and being anxious and the possibility of a thunder suit, that won't sort out it's problems will it?
This dog needs a new home, I don't know how your friend ever got the dog in the first place, do the dog a favour and tell your friend she would be better getting a stuffed animal.
I know I'm being very tongue in cheek, but the dog deserves someone who can give it time and lots of exercise being a gundog.
I'm glad that you care enough to see what we think, but I honestly would be on to the rescue and asking them to call in for a follow up visit. :-)
