I am fascinated watching Maggie's color changes. She had some big changes between 12 and about 20 weeks. Then everything slowed down and I thought she wouldn't change much more. Now at 9 months she is getting a lot more brown. Sometimes I think she actually changes in the night or between me leaving for work and coming home in the afternoon. Is there a typical age for this to stop or does it vary between dogs? I think she is pretty no matter what color but I do love the brown.
