They say there's nothing stronger than a mother's love, and video from India's Karnataka State proves that a mother's love isn't limited to humans. A loving mother cow followed a pickup truck as it was driving her two-month-baby calf to a nearby veterinary hospital. The affectionate mother never let the vehicle out of her sight as she stayed on the side of the car during the entire ride. The worried mom then stayed outside the hospital for two whole days waiting for the vet to finish treating her little loved one.
