Ruby was a year this past October. If I've read right a Yorkie's coat colors continue to develop into their 2nd year??? I can't remember how Lola went thru her color changes so many years ago. The reason im asking is Ruby's coat seems to have a chocolate/brown tinge to the blue/grey/black area. Can that be typical as they are maturing? Im just making sure its not because she is missing a nutrient or something as Im having a paranoid moment!
