Does your dog like to jump on you every time you walk in the door? Does he have a habit of trying to knock everyone flying with his jumping antics? To your dog, jumping on you is his way of telling you just how much he loves you, but it can be a nuisance, especially if you happen to be coming through the door with a load of groceries in your arms. One thing your dog knows for certain is that by jumping up on you, he is guaranteed to gain your attention. While this might be cute when your dog is a puppy, when he gets to be a full-grown dog, it isn't going to be quite as cute.
Teaching your dog not to jump up needs to wait until he has already mastered a few of the simpler commands such as 'sit', 'stay', 'no', and 'lie down'. Once he has mastered these simple commands, he will be in much better shape to start learning more complex commands and those that are put in place to control his excited and compulsive behavior. Much like any other command type training, you need to use a firm commanding voice without yelling. All you are trying to do is let your dog know who is in control, not scare him half to death by yelling at him.
While a puppy jumping up may be cute, when a big dog jumps up someone can be injured or something could easily get broken.
To get started training your dog not to jump up when he shouldn't, you won't need much: a bag of treats, a lot of patience, a quiet place to practice, and plenty of time. The most common commands used for this training are 'off', 'down', or 'get down'. It is important to choose a single command and stick to it while you are training your dog, to avoid confusion.
The most important thing to remember is that your dog is jumping up on you out of sheer joy. Your goal is to teach him that displaying his affection in this manner is not acceptable. However, you must remember that successful training begins with praise and that punishment in any form will never teach your dog anything more than to be afraid of you.
