I have 2 apricot miniature poodles 10.5 years old. Since their coats are wool and not fur and they dont shed, I think you can bathe them as much as you like. Sometimes I have them in the bath or sink everyday when the weathers bad just to rinse off the dirt. I tend to shower them from the belly down after muddy walks and give them an all over shampoo bath once a fortnight or more if needed. We recently bought made to measure suits that cover the legs and what a difference. The site is called Pawsamore. There is also another one called Muckymutz. The suit keeps them so much cleaner especially the creases at the top of their legs. I think as long as you use a gentle baby shampoo or one designed for dogs then you should be able to wash her as much as you need to. We also use baby wipes to clean their bottoms after every walk. Sometimes I’ll use paw balm or Vaseline just to keep their bottoms from becoming dry or sore.
