To get a dog used to stop jumping on people when you meet them, you can use some effective training methods:

1. Positive guidance:
Reward for desired behavior: When the dog approaches people without jumping, give it a treat or attention.
Using a word or command: When a dog approaches quietly, use a word like "sit" or "my legs" and give him a treat for it.
2. Ignoring the jump:
Unwanted behavior: When the dog jumps, you must completely ignore it. Don't touch him, don't talk to him and don't look at him until he stops jumping.
Repeat the process: Once the dog stops jumping, then you can return to the attention and give him a treat.

3. Routine training:
Practice with friends or family: Ask people you trust to come and practice with the dog. When they come into the house, give the dog a command to sit before he gets attention.
Teach him to sit: when he approaches people, give him the "sit" command. If he sits, he will get attention.
4. Using the strap:
Control of the dog: When you go out with the dog, use a leash to prevent it from suddenly jumping on people. Reinforce the instructions with a treat when he behaves well.
5. Patience and consistency:
Continuous training: it is important to be consistent. Every encounter with people is an opportunity to train the dog.
Long process: remember that it can take time, so be patient.

6. Preparation in advance:
Use carrots: If you know you are going to meet people, bring food treats with you that will attract the dog's attention during the meeting.
Preparation for situations: practice the dog in similar situations before the real encounter. For example, schedule meetings with friends or neighbors to train the dog.
7. Continuous training:
Maintain a regular practice: Set aside time every day to practice. Continuous practice can improve the dog's behavior.
Set small goals: Instead of expecting immediate change, set small goals and don't expect immediate change.
8. Attention to your energy:
Be calm: dogs are very sensitive to the energy of their owners. If you are tense or excited, the dog may react accordingly.
Keep calm: approach people calmly and do not give the dog the feeling that the encounter is too exciting.

9. Studying alternatives:
Alternative behavior training: the dog can be taught to sit or lie down when meeting people. This can be a good response to a jump.
Reinforce relaxation behavior: When the dog lies down or sits near people, reinforce this behavior with a treat or attention.
10. Using a jump trap:
Wait for the jump: If the dog jumps, let him skip the situation a little. Once he stops jumping, give him attention.
Marking good behavior: If he sits or behaves well, give him a treat.
11. Professional training courses:
Consider professional training: If the jumps continue to be a problem, a professional training course can help. A professional instructor can offer additional techniques and guidance.
12. Set boundaries:
Avoid opportunities to jump: Try to avoid situations where the dog can jump on people, such as keeping a leash when there are people around.
