Getting alittle gray

I noticed in the new Christmas shots I took of the dogs that Lola has considerably more gray and white hairs on her face than last year at this time. It's mostly on her chin, where has always has a touch of gray, but its quickly spreading. The first shot is below is Lola's baby grays, the next shot is from last year, and the last were just taken a week ago. I attribute the spread of the gray to her intense personality and sensitive little heart.
