Another thought is to use an enzyme cleaner which may get those "organic" doggy smells out better than any detergent...the natures miracle line of products is wonderful.

Aside from taking the dog to the vet re anal glands, I'd have thyroid checked (heard dogs with thyroid issues can stink). Can't hurt...

That being said, I do know someone where I used to live who owned and bred dogs, was a great trainer but his dogs were kennell dogs as his wife had bad allergies...While I have no doubt that those dogs were very well taken care of (and I had been to the kennel myself) they had that kennell smell you could smell if they passed you.
