On October 12, 2023, at Dalian Maritime University, an endearing video captured adorable images of an adopted stray dog named LeLe acting as a teaching assistant in a university classroom.

In this elective class called Pet Science, which focuses on pet-related issues, the teacher specially invited professional dog trainers to give lectures to the students. With their adopted dog Lele, they demonstrated the skills of jumping rope and skateboarding to the students, which left a deep impression on the class.

According to the filmer, this course is very popular in his school. Chinese netizens were shocked by the 12-year-old dog's intelligence and energy, reminding the filmer that the dog could even apply for a Guinness World Record.
