Hey, I'm new to this. I have a 2 year old female Yorkie. I have read that Yorkies should have their adult coat by 2 years of age however my little baby's hair is not growing very much. How do I get it to start growing? whats the best food. I am feeding her Royal Canine.I give her bath every 2 weeks. Any suggestions would be greatly appreciated. Janis and Zoey
