Thanks for the tips, however, its been a little more involved; and less. I decided to not take out the seats, but I did get some BlueMagic carpet stain remover. It has good reviews, though have yet to use it because of the more involved part (and rain).
I had discovered that the dog really only sat in the back seat; I could see the foot prints smeared all over the leather. I decided to tackle this with PurplePower and after cleaning the seat, I noticed how dirty the leather and the plastics of the interior really were. Basically I have been letting degreaser soak in on almost all the plastics. I have it slightly diluted in a spray bottle; saturate a panel or two, let soak, scrub and let sit, spray again and immediately wipe off excess. The result were astounding; didn't even realize how dirty the plastics were until I finished. As you could imagine, this has taken most of the day.
I will be going to a local car wash to do a thorough vacuuming; Wet/Dry Vac was too pricey to invest into at this time, and isn't really necessary at this point. Once I get back home I will use the 'New Car Smell' interior cleaner/shiner (waiting for now as I will be spot checking for areas that were missed when degreasing). Then I will move onto the carpet and hopefully see good results as I'm close to having a like new interior at this point! Ill take pics when all finished (would have taken before had I known it was so bad).
I'm sure I wont get that 'new car smell', but it does smell like it will be some good stuff. As of now it certainly smells better, no more dog smell at all.
