Smoke smell from the chimney/fireplace

You could see if anyone you know has access to any upholstery cleaners, like "Bissell Little Green Multi-Purpose Compact Earth-Friendly Deep Cleaner" or you can try and find some place where you can rent a Rug Doctor with an upholstery attachment, you might be able to find one at hardware and some grocery stores depending on location. You'll probably want to use some odor neutralizer in with the water while cleaning which I think rug doctor sells a specific one to use with their machines if you go that way, but baking soda might be just as effective, I've never tried that method.

I have used that mixture with good success. Make sure to wipe down everything that the dog might have come in contact with, and I mean everything. Floors, walls, trim, doors, etc. You might need to repeat the procedure a few days later.

The skunk odor tends to linger quite a bit and you will find that it gradually reduces in intensity over time but is still evident. Anytime your dog gets wet you smell it, likely for months!

If it is really bad and does not go away you might opt to bring in a professional cleaning company who will have stronger chemicals to deal with it.
