This is said of my breed also. I went to shows with a lady who owned 20 finnish Spitz. I wouldn't say they are odourless (after all tehy breath and also fart at times) but they are a klot less doggy than many breeds.
My Father who is not into dogs at all reckons they smell if he has had them in his car, but then he is particularly fussy, and thinks dogs like Labs absolutely stink.
In my expereinces the Northern (spitz) breeds have lwast doggy smell about them, though even they when wet will give your car that wet rag smell. :D
