Happy is nearly 4 years old (in 6 days), and last night I gave her a bath and noticed that the side of her white leg facing outward is freckaling, it is not as noticable when her hair is dry but the freckles are getting darker and more prominany, when its wet the spots are very clear, they are so big and close together that it is almost solid black. is it normal for a dog to start to freckle this late?
