No room remained for another body. Well, almost. With her tongue hanging out and tail wagging, Molly — a pit-bull mix — unleashed a bundle of energy as she was led from her kennel. She jumped onto the bench, forcing Perez to relinquish her seat. "She was so comfortable, and she could be herself around us,'' Perez said. "She was all over Raven and everything. It was nice to have that feeling, that comfortability.'' First days of school come with introductions, and Molly was just making hers. She was not the only one during the first session of Lake Technical College's new veterinary assisting program. Eight of the 11 students who signed up were in attendance, said Melissa Stephan, the college's director of curriculum and instruction.
