Although it seems harmless and fun, an overexuberant dog that jumps up as a standard greeting can injure people, especially children and the elderly. To help remedy this situation, it’s important to try to recognize when your dog is more apt to exhibit this behavior. Dogs often jump when people come into the dog’s home, but it could also happen in the dog's yard, in a park, and while on a walk.
If this frequently happens after your dog has been at home alone, plan to exercise him to burn off some of the excessive energy. Then train your dog not to jump on people by having him sit and stay when guests arrive or when people approach. You can also try distracting him with a favorite toy or treat or putting him on a leash or behind a gate — and away from the door — when people first enter the house. Then when your dog is calmer, or in a sit/stay, you can remove the leash and let him greet the guests in a calm manner. Your guests or kids can help by not petting the dog or giving attention when the dog is jumping on them. This helps remove some of the positive reinforcement your dog receives when someone reacts to the jumping.
