My dog is so excited when ever someone comes in the home. Any family member can leave for may an hour or just go upstairs for maybe an hour and my dog acts as if she has not seen us in years by jumping on us constantly. It's so annoying sometimes.
Like one other person mentioned, you could try ignoring and not giving ANY attention to her until she stands or sits rather than jumping. Give her attention as soon as she stops and praise her, so she can see what it is you want her to do. If she starts to jump when you're about to pet her, keep ignoring her. Ignoring means not reacting in any way to her, not looking at her, not speaking to her.
Ask any guests who visit to also ignore her until she is no longer jumping. The more practice she gets with doing the right thing, the more the right thing will become a habit! Invite guests over so she can practice with strangers, not only with family members.
Good luck!
Some dogs find the act of jumping up rewarding by itself (I've got a jumper - she LOVES anything that gets her feet off the ground), so you may have to get creative to make not jumping more rewarding. Dogs want to greet us up close, like they would another dog. They can tell a lot, like how we're feeling and what we've been up to by sniffing around our mouths (and other parts...), and they like to check in on us when they haven't seen us in a while. Since dogs don't experience time the same way we do, a while can be anywhere from minutes to years. One of the things you can do to discourage jumping, then, is to get down on your dog's level so they can fulfill their need to check in on us without jumping.
When that's not practical right away, I find holding my arm straight out and using my hand as a block or raising one knee between me and my dog is effective for preventing her from jumping up. Then I can ask for an incompatible behavior, like sit or wait, which gives me time to meet the dog at her level (keeping my hand or knee in place as needed in the meantime). I've also taught my dogs to jump up and get down on cue, so I can give them an opportunity to jump when it's appropriate as well as let them know when that time is up.
For greeting others, I give reminders not to jump as we approach, and reinforce that whenever possible by stepping on her leash so she's unable to jump. Having the cue to get down is also handy for when my prevention is ineffective.
Our dog gets so excited to see us even when we have been gone only a few minutes. To him it seems like an eternity. He also wants to jump up on Pet Parents when they come to drop off or pick up, neighbors when we are out for a walk, and anyone else he knows. We tried to ignore him, turn away when he does it but that hasn't worked very well. He knows "sit" "down", and other commands but I have taught him "Off!" instead of "down". "Down" means to "lay down". "Off!" means "No jumping, Paws off the counter, etc". The word "Off" has worked very well for us and that has stopped him from jumping up.
You can try to ignore the behavior by not giving her ANY attention (negative or positive) when she jumps on you, then praise her when she is standing by you rather than jumping. If she is a larger dog, you can also try lifting your knee up when she jumps to prevent her from being able to place her front paws up on you.
You can start to teach your dog better manners in just a few steps!
1 - Establish yourself as pack leader.
2 - Don't shower your dog with affection when you walk through the door.
3 - When your guests arrive, ask your dog to sit patiently.
before opening the door try to calm him down, use your body to block him. Slowly back him up away from the door, wait until hes calm and relaxed before opening the door , You would have to try this multiple of times until he gets the hint, but try to stay calm and focus and besides talking to him, make a quick sound with your mouth every time you're slowing moving him away from the door . I hope it helps .
