You guys know now with Daz Studio 4.12 you have built in Strand Based Hair which allows you to literally put hair on ANYTHING and grow it in any direction, length or shapes you want. So if you want bristles, thin hairs, curly hairs etc you have that control. People are making Body Hair, pubes and treasure trails, facial hair and head hair with it and many of the new products sold on Daz are made using it.
So you can put hair on the K9 dick all you want now!
