Dog Training Ultimate Guide

My dog jumped on the top bunk of my bunk bed twice but now she wont do it. How can i get her to jump up there again? I have tried making her run and jump and tried coxing her with a toy and food. Nothing seems to work.
Shes a chocolate lab/ setterand she has jumped higher than that before.

When I eat my dog jumps on me.I wonder why I need help.Sometimes he even gets on the table.My dad gets mad when he does it. I need help.

She jumps up when there’s an animal moving, standing, making noise or even a baby and sometimes humans too. She’s 2 years old and she always runs back to our couch like she’s scared or maybe she’s jealous! She’s not good with other dogs so does that have something to do with it? Do you think she’s scared or jealous?
Is there a solution to it?
Thanks for some of your great answers! they have helped we had thought of some of them but we just didnt know if it really was the right thing to do!

My friend’s dog was trying to jump on the trampoline and just was not getting that there was a net.
