We have been bringing our animals to schools all over the LA and Orange county area for over 20 years. We are very well- versed in handling large numbers of children. FOR THE PUPPIES:  We have the children take turns inside the pen, doing multiple groups of kids for a certain period of time, within the length of time we have been scheduled for. FOR THE REPTILES:  We recommend that you break up your total time into smaller shows so that the kids can have a more hands-on experience.
