Abstract: An animal self-carried hydrating system comprises an animal harness, a fluid container for holding the fluid, and a fluid dispensing mechanism. The animal harness is securable on the animal by a fastening system. The animal harness has a fluid pocket for holding the fluid container. The fluid dispensing mechanism is attached to the fluid container, in fluid communication with the fluid in the fluid container. The fluid dispensing mechanism is such that it can dispense fluid from the fluid container to the animal while the fluid container is in the fluid pocket.
