What a pretty girl - love her "basenjitude"!
I never bathe my eleven-year-old basenji girl, and she never, ever smells - but her feet have that lovely basenji "Frito-feet" odor. I don't know how it's biologically possible for a dog to always smell fresh, but basenjis do. Normally I'm allergic to dogs but don't react to her, and never had allergic reactions to any of my eight basenjis over the years.
A meal all my dogs enjoy is one can each of sardines in olive oil with skin and bones, which will add healthy fats, added to a reduced portion of their normal food. I empty the oil into their bowls too. They get this occasionally, maybe once every two to three weeks.
Sometimes I'll fry eggs in butter for us, and also for the dogs for one of their meals. They're on a commercial frozen raw diet by Darwin's. Eating coconut oil is supposed to be good for dogs in moderate amounts too. I don't think any of my basenjis would tolerate coconut oil applied externally; they'd lick themselves clean which would be okay in that case.
