Jumping

Let your dog drag a leash.  When he starts to jump, just step on it about a foot from the collar.  I use OFF as my word, but you can use whatever makes sense to you, and to him.

The most reliable way is to teach the dog to SIT when greeting people-- dog is not allowed to receive any attention from visitors unless in a sit. Requires "trained" visitors to teach this. Add a dog that offers a "paw shake" along with the sit and you'll have a dog everyone wants to meet.

And while you're working on the "sit" to receive attention - one thing you can try when he does jump:  cross your arms and turn your back on him.  Use your body to "block" the jump.   After a few times (maybe more) of  using a combination of asking for a sit and blocking the jump - he will eventually sit as soon as you block (he's learning what you want and he doesn't like being blocked!)   And eventually, he'll just sit.  Just be consistent - tell him to "sit", praise him when he does it, block him when he jumps, tell him to "sit" again, praise him - block when he jumps.  Slick is still very tempted to jump on certain people - but as soon as they cross their arms, he sits... 

Scout used to be a jumper too!  We used Christine's method, arms crossed and turning your back. I also make a point not to make eye contact until butt is on the floor.  I also gave an off command followed by a sit command when we first started.  I also used treats, but ultimately attention is usually enough! Afterall that's usually why he was jumping!
There's nothing funnier than scout when he really wants to greet you. Butt on the floor wiggling a mile a minute, blowing air out of his lips in excitement/anticipation.

Hello there

All these are really great ideas that also really work well - IF and only IF you train your visitors first. []

I always found people much harder to train than dogs, and those people can quite foil your nice sit-for-attention training attempts. Thus, make sure that until the dog has learned to properly greet people, he only gets to meet people which have been properly primed beforehand. One person going "oh let him jump up! he is so cute!" can make the previous weeks efforts to naught.

The 'stepping on the leash' technique can help if the dog is extremely active. Myself, really hyper and powerful dogs I will have restrained on a wall-hook with a leash (that avoids having a hundred pound dog jump into the back of, say, a hundred pound lady [] ). While on that leash, the visitor moves closer to them when they sit, and moves away from them (and turns away) as soon as they get up. The dog will quickly learn that he, the dog, controls the situation: 'I sit, person comes closer, I stand, person walks away... '. That physical restraint then is gradually faded. Once that works very well, a person can hold that leash, then one can have the leash on the floor (and step on it if needed), and eventually the leash is completely removed, and simply turning away will be enough of a reminder if the dog ever tries to reintroduce jumping.

As a methodological corollary, while you do these things, you also ought to teach the dog when it is ok to jump up on you. Teach the dog to jump up on you on cue, and when he is up, to go 'off' on cue. What you get is a dog that sometimes can jump up on you or others, but only when you says so - it becomes a reward that can be used to teach or reinforce other stuff! - while he also learns the 'off' command. Nifty, eh?

Good luck and let us know how it goes! []
