When Inka was a baby and new here, I just HAD TO bath her butt. She had diarhea and with all that long hair, there was no way she could keep it clean... . No problem anymore now
Maya doesn't need baths either, as she is almost constantly groominh herself, or napping
When I got our Zazou, I was planning to bath her after a few days, as her little white boots were so filthy. But, as soon as she felt home here, she took care of that herself! Perfectly white boots now, and NO bath needed !
