Is that someone with a puppet string in the ceiling attached to that dog's tail? No, it's German Shepherd, Nayla (nickname "Pixie") who simply can't control her tail when she's in heat. I've owned 4 female German Shepherd's before Pix and not one did this when in season. Since then Nayla's been allowed to have a litter of pups, which she was quite happy to procreate! 4 beautiful pups, two I have kept as personal pets and two went to very good friends and homes. Arf!
