Hi..I started bathing our first yorkie Shasta when we adopted her and she was nine weeks. Mica was 14 weeks and I have bathed her weekly since the day I got her. I also do my own grooming and tend to clip her nails. trim her ears and paws each week. It seems easier to keep grooming up that way and helped her to get used to regular grooming much better. I know that our breeder had been bathing them though prior to us adopting them but I never did ask at exactly what age they started. I imagine some of the breeders here on YT would know the answer to that quesion.
