Thanks you guys. It's exciting to think Thor might keep changing colors no matter what age. It keeps things fresh! I thought yorkies stopped changing by age 3. I haven't seen any drastic changes in the past few months, but I guess when you obsess over your dog as much as we do, you watch every hair.
I wonder if it is related to diet or life style?
Love that some dogs find it too onerous to change colors all the time and stick with what they have.
