When your dog jumps up on you, instead of backing away from him, walk into him while holding onto his front paws so he cannot drop down.  Say nothing and don't look at your dog.  Instead, look up at the ceiling and ignore him.  The dog will be uncomfortable and will try to drop his front paws to the floor so he can jump up against you again.  Don't allow him to do this.  Keep the dog standing upright on his hind legs until it is uncomfortable for him and the dog clearly indicates that it wants you to release his front paws.  That is when you can release him and say, "Off."  Use a firm tone but do not yell at the dog.

Most likely, your dog will jump up on you right away.  Simply repeat the process as many times as it takes until he stops trying to jump on you.  Remember to keep your voice calm and not to yell at the dog.  This is not punishment.  It is simply showing the dog that it is not comfortable to jump on you and that he won't gain your attention by doing so.

When your dog is standing on all four feet with a baffled expression, tell him dog, "sit" and praise him and give it a treat.  You have just shown the dog a positive behavior that he can do in order to earn praise instead of jumping up on you.  Praising the dog at this point will probably cause the dog to jump up against you again.  Simply repeat the process.  You are showing the dog how to greet you and soon when you walk through the front door your dog will greet you by sitting calmly at your feet.

It is important to watch the dog's behavior and tell the dog to sit before he jumps up on you.  In this way, you are again showing the dog a positive behavior to substitute for jumping up on you in order to earn praise from you.  Your dog is seeking attention from you when it jumps on you so give him another option so he can earn the attention he needs.

If your dog jumps on visitors, take the time to put a leash on him and tell him to sit BEFORE you open the door to greet your visitors.  Dogs become excited when new people arrive.  Everyone is happy to see one another, the visitors smell different to the dog, and the dog naturally wants to be part of the greeting process.  By giving your dog the sit command, you are providing a positive behavior that he can do to earn praise and attention from the visitor.  The leash maintains control so you can keep him sitting while allowing visitors to pat and greet the dog in a calm manner.  Keep a leash by the door so it will always be available when visitors arrive.

If the dog continues to be excited and bounces around the room after everyone is seated then keep the leash on the dog.  Don't shut him away in another room or put him outside.  This does not teach him anything except that when visitors arrive he is no longer allowed to be part of the family.

To teach a dog to stay off the furniture or from standing up on the counter to check out any possible goodies AKA "counter surfing,"  place him on a leash and let him drag the leash around the house.  Watch him closely as you want to redirect the dog before he actually jumps onto the sofa or stands up to counter surf.  The key is to redirect the behavior when the dog is thinking about doing something that is inappropriate rather than after he has already committed the crime.  Therefore, as soon as you see that he is about to do this, take the dog by the leash, pull the dog away from the sofa or counter, and say, "Off ."  You can redirect him to his bed where you can praise him and offer a treat or redirect him to a toy.

This should be repeated every time not just some of the time.  If you correct and redirect the dog 90% of the time, your dog will remember that 10% of the time this behavior was ignored (translates to 'allowed' in the dog's mind) and he will continue to try to do it.  Remember counter surfing and lying on a nice, comfy sofa are high rewards for your dog.

Will this prevent your dog from doing these things when you are not at home or if you leave the room?  Probably not, especially at first.  That is why when you cannot "watch" your dog, the dog needs to be placed in an area where he cannot make mistakes.  Dogs that never receive gratification from doing an inappropriate behavior will make fewer mistakes.  Remember that they respond to rewards and finding a tempting morsel on the counter is a very rewarding experience worth repeating.

For your pet's safety, never leave a leash on your dog when you are not supervising him.
