I bathe lola once a week and sometimes every 5 days

I use yorkie sheen and splash, they also have a detangler that works great for long or short hair yorkies, the smell is amazing and so far is the best shampoo and conditioner i have tried. A lot of YT'ers use that brand too.
here is the link to their website:
Yorkie Splash and Yorkie Shine | Yorkie Shampoo and Yorkie Conditioner
They offer a discount for YT members. Good luck!
