Here are some tips for effective begging. First, you sit politely in front of the human with treats. Then, you put on your cutest, most winsome dog expression. You must appear humble, worthy, and respectful. Once you've gained a sympathetic advantage, treats are almost 100% guaranteed.
Begging is best accomplished from the sitting position. Ears should be cocked forward. Tails should not be wagging. Maintain constant eye contact and strike a fine balance between pride and pleading. Try to look temporarily satisifed and appreciative while maintaining the constant pressure for more treats. By practicing and perfecting these techniques, your begging objectives will be succesful.
