The present invention provides a cross-flow type drying apparatus for a pet, that is capable of quickly performing drying by blowing air uniformly on the entire body of a pet and simultaneously facilitating drying by reducing the amount of stress that a pet is subjected to. The cross-flow type drying apparatus includes: a main body case defining an outlet and an inlet and including a heating member installed within; a cross-flow fan installed in a longitudinal direction within the main body case to rotate; and a stand coupled to enable the main body case to pivot to a predetermined angle. This configuration can reduce drying time and easily perform drying the pet, and can lower manufacturing cost to reduce the financial burden placed on a user.
