As far as I can tell there is no pocket to speak of. Just looks like a reg dog tail. Weird huh? First I have seen of it too and I love it cuz she can wiggle her bootie like no other than add in that tail and you cannot resist the wiggle.
The spots are looking better maybe? Like they have dried out I suppose but she does still have many wanna be red bumpy looking things that I am keeping creamed as well. She is so spoiled she lays down for me to put the cream on and she eats up the belly rubdown she gets.
