This dog really is a man's best friend: Devoted pet is filmed chasing ambulance down the street after its owner is taken ill and rushed to hospital

The dog's homeless owner was taken to hospital after having a seizure in Goiana, Brazil - where despite the speed, his pet kept up with the ambulance for several minutes. It started by bounding along in the middle of the road, visible in the wing mirror (top left) before crossing to the pavement (top right) and carrying on alongside the vehicle (bottom left). Eventually the crew took pity on the dog and allowed it to come aboard (bottom right), and it joined its owner once he was laid out on a stretcher in hospital (inset). Paramedic Celiomar Ferreira do Couto, 42, who made the video, said: 'I've done this job for 19 years. I've never seen anything like it'.
