That is basically true about the dog smell, but not always. I'm a dog owner, but my dog is primarily an outside dog. She only comes in occasionally, but I don't have carpets or upholstered furniture that would retain a smell even if she had one. I think that's key- If you have primarily hard surfaces, with covers, curtains, etc, that can be washed, there's really nothing to hold the smell. My dog, a Korean Jindo, is also a breed that actually doesn't smell like dog. Many of my non-dog owner friends have commented on this- they'll pet her, then smell their hand and say "That's weird-she doesn't smell like dog-she has no smell at all! ".
Nor am I immune from dog smell in other people's homes.
However, she does reek in the many months of rainy season here when her fur is constantly damp. And I can assure you she smells really bad to me then, as well.
