Sniffer dogs play in incredibly important role in the armed forces, assisting bomb squads in detecting unexploded devices in order to de-activate them and save countless lives on a daily basis.
For many, life after retirement can be bleak, with no home to go to as most people prefer to adopt puppies.
However, one of the army's top dogs - Jake the springer spaniel - has been adopted by former soldier Andy Hawkett after the two formed a strong emotional bond while on tour together in Afghanistan.
Speaking to the Express, Mr Hawkett has described how Jake helped him through a particularly difficult time when his team was caught cold by a bomb, and had to spend more than a year trying to adopt the dog following his retirement.
Happily, Jake and Mr Hawkett are now re-united and living happily together at their home in Kent, although the pair's walkies may not be quite as exciting as they used to be.
