Rosy's young and foolish, as many pups are. She simply bulldozes her way around without any grace. There is an art to begging that requires patience and subtlety.
Rosy can whine, jump around, and paw at the human's legs all she wants. I know the true secrets to getting the good stuff - sit in the human's line of vision and give your best, most pathetic-looking slump and sad face. If needed, add a cute tongue sticking out and/or uncurl the tail.
Works every time.
