The PETRY project aims to help dog owners who struggle to provide their pets with sufficient exercise. The service connects dog owners with dog walkers, promoting the health and well-being of both parties through shared activities. PETRY uses an intelligent matching system to recommend the most suitable walker and offers products to enhance interaction between the owner and the walker. The platform also enables users to book companionship exercises and community pet parties, making it a comprehensive C-to-C product service system.
