The Question
“Daisy has reddish hair around her privates, and it’s dark in the creases. Also looks like she ate something reddish around her mouth. She is white. Not bloody not sure what caused it.” – Rita
Quick Info about Daisy
Hi Rita,
What you are noticing with Daisy is something I see quite often in white-coated dogs, and it can look alarming at first glance. That reddish discoloration around the mouth and near her privates is most commonly related to saliva staining of the fur. Dogs naturally produce compounds called porphyrins, and when saliva sits on the hair, especially in lighter coats, it can leave that rust colored tint over time. The darker areas in the creases are usually where moisture lingers, which can lead to staining and sometimes mild yeast overgrowth.
Even though it looks unusual, this is not typically something to worry about, especially since you are not seeing fresh redness or discharge. It is more related to moisture and repeated licking in those areas. A gentle routine can make a big difference here; lightly cleaning and drying those regions helps reduce buildup and keep the skin healthy. It is also helpful to pay attention to how much she is licking, since an increase can be a sign of irritation or underlying discomfort. If the skin starts to look thickened, develops an odor, or the licking becomes more frequent, having your veterinarian take a closer look will help keep her comfortable and prevent progression.
Kind regards,
