For the jumping up, I found what worked with my Sting was to turn my back. I tried everything else stepping on his toes, kneeing his chest. He just thought I wanted to play. The ignoring worked. For tug, it doesn't make the pup agressive, but provides an acceptable outlet for the prey drive. Be sure to let the pup win after a struggle as that satisifies the prey drive. At your pup's age, she may really enjoy a flirt pole.
