They are man's best friends - well Neil Powell's search and rescue dogs certainly are.
Co Down man Neil and his dogs have travelled the world helping to find and rescue people trapped after devastating earthquakes in countries like Turkey and Pakistan, but also ramblers caught by sudden storms in his native Mournes.
Many people are alive today because of the work of Neil and his dogs, but sometimes - as after the Lockerbie Pan Am flight bombing - their role is to recover bodies or evidence. It's harrowing work, but the rewards of saving lives are enormous. We should all be grateful to the unsung heroes like Neil and his dogs who live in our midst.
