Beg
You can train your puppy to beg if she knows how to sit. You should get your puppy to sit and then move a food treat up and down. You can use the command “Beg” when she nears upright position.
Thereafter you can release her and give her the food treat. Gradually she will understand the meaning of the word “Beg” and come in an upright position every time you ask her to do so. However, you have to be careful not to train her to beg when you are having your meals because this might induce the bad habit of begging in your puppy.
