My mom gets compliments that her apt doesn't smell like dog at all. Or course, I'm the one putting all the effort in keeping everything clean.
I bathe Kaji once a week, clean his wee wee with pup moisturizing wipes after he goes pee and clean his paws and face with a warm towel at night. Call me a freak, but Kaji sits on the couches, sleeps with me, and hops on all the beds. I'd rather keep him as clean as possible without harming his skin (causing dryness) and having him walk around smelling like pee. My friend's dog smelled a little and only got baths once every 2-3 months.
