Hello;
My Yorkie has a spot of tan now on her gray head that I noticed when combing her today. It had to have just came in like THAT! I brush her everyday.
Can you please look at this spot and tell me if perhaps this is the start of her gray hair turning to tan? 
I had given up all hope of that happening. All other yorkies I have had a pleasure of knowing all had no gray so this is new to me.
I have even tried to scrub it off
ITS HAIR!
So will the spot continue on growing as it pleases around the top of her head? If so, how long does that usually take?
Thank you very much! This is exciting to me and my girl! I included images of her and the spot - cell pics so they arent good but gives an idea.
I should add her age - she is just shy of a yr.
