Female Dane keeps on Jumping on People

[Quadro]

Hello Everyone, my 9 month old female dane has suddenly developed a habit of jumping on people. What should I do to stop her from doing this. I say "NO" to her but she does not listen at all. But when she is outside the house like in Parks, etc she does not do it but in the house or other places she is comfortable in, that is where she does the jumping. Thanks

Teach her a sit-stay. Cannot jump on anyone if complying with this command. Teach the "OFF" command properly & it usually only takes one lesson, so maybe what you need is to get a trainer in or enroll in a basic good manners/obedience course with her? Good luck.
