Massage therapy

Massage therapy improves blood flow, reduces muscle stiffness, and promotes relaxation. By increasing circulation, massage helps deliver oxygen and nutrients to tissues. It also stimulates the lymphatic system, reducing swelling and supporting immune function. Massage is beneficial for pets with arthritis, injuries, or post-surgical stiffness.
