Does this sound like the above. Dog holding hind leg up really high, doesnt seem to be in pain, doesnt whimper etc. If I rub the leg for a bit she usually puts it back down and walks off normally. Cant hear anything clicking into place. Happened once last year but twice today. Thought she'd done her cruxiate ligament the first time. She will usually cry out if I step on her foot or when Im trying to pull a knot out of her hair so thought she would cry when her leg went if it hurt.
