A pet care management server for providing pet care services includes a communication unit that communicates with the outside through a wired and wireless communication network and a controller that acquires information necessary for the pet care service based on the information received through the communication unit. The controller generates information necessary for the pet care service, and transmits the information to the outside through the communication unit. When one of a pet transport service, a goods delivery service, and the total service combined with the pet transport service and the goods delivery service is reserved by a user terminal, the controller determines a vehicle for providing the reserved service among waiting vehicles and a pickup time at the departure point for the pet transportation based on the reserved service time, the departure point and the destination of the pet transportation.
