An unspayed dog that gets loose or is tied out is a future mother dog. PLEASE get her spayed! It may also make it a little easier to control her as she may be getting loose to look for a daddy. Our trick for dealing with this is to anticipate the jumping (you need to be an adult to teach this) and as soon as she goes up, raise your knee quickly and thump her in the chest. It will knock her backwards without hurting her. Accompany this with a loud "no!" It takes a little practice for you and her, but I have never had a dog that this didn't work with. In my experience turning around and ignoring the behavior, even walking away (especially if they're contained)...will get a faster response than putting up your knee. They are looking for attention and even negative attention will do....the knee will work eventually, but they'll learn faster if they get completely ignored when they behave that way. Everything else is pretty much on the money. It sounds like she gets basically no exercise and needs a LOT. To get her to be able to walk and come back if she is loose, I would start by working on "come" while she is on a training line (even if it is secured to the ground in some way). A training line will allow you to get her attention if she isn't listening, and is a way to reel her in. Find her favorite food and use that as her reward....do NOT give it to her if she isn't doing something for you! There is a lot more to training that was is going to get mentioned in this thread...you really should at least take her to a training class.....or at the very least get a couple training books or find some good training websites.
