Arrrgh---JUMPING!!

When Sally jumps up remove her from the situation turn and walk the other way or remove her from the room (sort of like a time out). Praise the times that she doesnt jump the hope being that eventually she will realise if she wants to stay and greet people she needs to keep all 4 paws on the ground!!! 

Good luck   

I agree that if Sally is timid, I wouldn't want to do anything that might make her feel like having people around is not a great thing...
 
So...  I think I would do it by teaching "off" or some command for 4 feet on the floor and each time she jumps, say "off" - no emotion, not at all angry.  Once 4 feet are down - it is GOOOOOOD doggie and treat.  When she jumps on others, the same.  Eventually she learns that when she sees new people and all 4 feet stay down, very good things happen including treats!
 
You could also try training some kind of "say hi" trick.  Maybe when guests come Sally can sit and wave for treats...
 
The key is to associate greeting people with a behavior that is mutually exclusive to jumping (this is in one of the books I recently read - maybe "Culture Clash"??).  So, if she is greeting the guest or you correctly, there is NO way she can also be jumping up.  If you associate great things with the greeting that is not jumping, and you reinforce it like crazy, it should fix the problem. 
 

When we first rescued Sassy, she was already a big lab and also real mouthy.  She'd jump up and try and mouth your arm all the time.  She also had fear aggression, so reacting in a harsh manner was counterproductive.  I found that really enforcing "sit" everytime she jumped up and then rewarding her by petting her (rubbing her chest for a few seconds - which she loves) stopped the problem.  She honestly never jumps on us or anyone else and hasn't for a long time.   

dogs jump to get a reaction (good or bad.) if she jumps on you or anyone tell them to turn away and ignore her. then tell her to sit down and praise her when she does that. she will learn that she gets attention when she is sitting and is ignored when jumping on someone.

Hello there []

Kenny's Mom is right on: the best way (talking non-aversive methods here) to teach a dog not to jump is to bodyblock jump attempts (leaning forward into the dog when he tries to jump up, not away), and at the same time turing your side to him, and averting your head and gaze. The second he does not jump, you reinforce him with praise, treats, attention. The microsecond he starts jumping again, you turn away once more. All family members must do this at all times (much swifter to train btw than trying to teach the dog to sit; that behavior takes much longer to ingrain, and most ppl do not care if their dog sits or not; all they want is for the dog not to jump). Once this works well with the family, have friends come over that are coached as how to act. The dog can under no circumstances have contact with anyone not playing by the rules until this new behavior is well established (otherwise you end up with immediate regression and a world of trouble). You will be amazed to see how swiftly the dog can learn that jumping up is the one sure way not to get what he wants. []

Good luck!

Hmmm...is there any way to modify above method when we HAVE to be around strangers?  We found that for working on the timidness, Sally does best of she gets out in public to interact with strangers a minimum of once a week.

Hello []

Well, this should not be a problem, and yes, it is extremely important to keep your dog well socialized. But those two things do not have to interfere if you think about it: the do-not-jump training is done at home, off-leash. I would expect that when you take her out for walks to see other people and dogs, you DO have her on a leash. Being restrained that way, I cannot imagine how she can jump up and forward onto strangers (if you cannot control her for now on a regular collar, use some sort of halter or gentle leader or a prong collar - however, make sure you know or educate yourself how to use those tools properly before using them!). If a stranger does want to approach and pet her, my belief always is that it is the stranger who wants something from you. Being that as it is, one can politely ask them to wait a moment, then give them a three-sentence idea of what one is teaching and what they must do if they want to still pet that dog. Some people will say they have no time, most - in my experience - rather seem thrilled to teach a dog something. If you allow strangers to participate in this manner, make sure you 1. step on the leash to inhibit jumping before it occurs (avoid putting pressure on the leash while the dog does not jump, as this can cause an opposition reflex) 2. be ready to remind the stranger to "turn away quickly now!" if the dog attempts to jump 3. pull off the dog as fast as possible if he manages to jump up (fast does not mean violently btw). The bottom line to remember is that every time a behavior you want to extinguish gets reinforced (with a successful jump-greeting in your case), it will add another few days of time it takes for the behavior to extinguish.

Oh - and always stay patient. Ingrained behaviors like this do take some time to go away. But with some perseverence you will prevail. []

Don't let her jump? Make her sit, then give her TONS of attention.

I agree with aussiegirl.  Sit is a great alternate behavior. 
Most people have problems with jumping because they fail to realize that they are almost always providing some sort of reinforcement for it (and usually it's variable reinforcement, which keeps the jumping happening even longer).  They shout "off" (means nothing) or "down" (wrong command), or they push, pull, shove, or look at the dog. 
My best success has come with ignoring jumping completely (that means turn away, make yourself incredibly boring, no talking, no eye contact), and reinforcing the dog for sitting.  What needs to happen is that the dog is left dragging a leash.  You step on the leash and ask for sit.  Dog sits, you reward.  Dog jumps, he self corrects.  If the leash is not on, he gets ignored for jumping, and rewarded if he sits on his own.
For guests, let them in on the secret and park a bowl of Cheerios outside the door.  Dog sits to greet when they ask, he gets one.  If he doesn't, well you are stepping on his leash way before the door bell rings (that's what cell phones are for LOL).
Seems like a lot of trouble, but it works.

You idoggers are so ahead of the times.  []  At least, ahead of the backwards thinking where I live.  [] 
None of you mentioned the "Knee in Chest" move that New Skete, the trainers AND vets around here all seem to use.  [:'(] 

Sigh.  I wish people were more animal aware around here.

Dasher is a notorious jumper. Me and my SO do a pretty good job on ignoring him when he jumps on us at home, it seems to be working. The tough part is when I take him to the office or any other public place. Strangers can be my worst enemy [] Dasher is super friendly so he is always eager to meet new people. When we meet new people, Dasher starts jumping, I tell him "off" which he knows and he will listen, but then the strangers will coo all over him and say "its ok, I don't mind if he jumps" and they start talking baby talk to him and he goes crazy and wants to jump up again [:@] Then they look at me like I am the evil step-mother when I kindly say "well, he is not allowed to jump" [8|] Oh Well!!
