Our puppies went to a pumpkin walk at the Roger William Park Zoo last night.  The pumpkins were lit with candlesand LED lights and the trail was extremely dark.  The crowd was extremely slow moving, but it was PACKED with people.  Even with flashing or clow in the dark collars on (thank you Lee and Lisa) most of the dogs all got stepped on, shuffled into, and tripped over. 
We got to see how they might potentially react in this situation with a client~sniffing peoples hands and other body parts (sorry!!), licking people's hands (there were food and drink vendors there), saying hello to babies in strollers before being given permission, etc.  Having to give attention to handler with strong predator and food smells in the dark was truly a challenging trip, but they all did pretty well. 
Thanks to Lee, Jenny, Rich, Lisa S, Lisa G and Lisa M for coming with, the artwork was truly worth the trip!
