Thor will be three in August. I still see changes in his hair color sometimes; he has some very dark blue on his shoulders that seems to be growing out, so his entire back is the same color silver.
A few months ago, his chest fur started turning bronze, the same color as his muzzle. I really liked it. The consistency of the hair seemed a little different, more coarse than the rest of his hair, which is extremely fine and silky.
I've noticed now that his chest hair color is turning BACK to the original light apricot. The ends of the hair are the dark bronze, and the roots are almost white.

I'm sort of sad to see the bronze go. Is it normal for yorkie hair to go back and forth like this?
