Set up seminars on domestic house dogs. Give the backround and how they became domesticated. Explain a little anatomy and work into nutrition. After lunch explain the attack nature and how a small dog can be hurt if not killed by a larger dog. Always set up a way to protect a small dog. Like trash cans throw the small dog in the large trash can. Be defencive no dog perks and watch whats around you ,you can always stop and turn around if a large dog approches. But have fun most of all.
