During the summer, I've been giving Cassi a bath every 5-7 days. I noticed after I bathe her, she starts to get oily on top of her head and around the ears on day 3-4. Currently, I've been using the Petco SPA shampoo/conditioner to wash her from head to tail. Following that I use a conditioner just on her body for every other wash. Now that winter is arriving, how often should I bathe her? Also if you have any product recommendation, it would be much appreciated.
