An animal tracking device for tracking an animal shot with an arrow. The animal tracking device may include an antenna, a controller, an accelerometer switch, a battery powering the controller and/or accelerometer switch, an animal attachment component, and a housing physically connecting components of the animal tracking device. The accelerometer switch may measure an amount of G force it experiences and send an interrupt signal to the controller when the amount of G force measured is at or greater than a threshold amount for a threshold amount of time, indicating that the arrow has been shot. The controller may send wireless signals to a receiver via the antenna in response to receiving the interrupt signal. The housing may be detachably attached to the arrow. The animal attachment component may attach to an animal shot by the arrow and force the housing away from the arrow.
