Forces News has been looking at some of the roles military personnel play across the world.
For the 1st Military Working Dog Regiment in Sennelager - the only operational unit in the Royal Army Veterinary Corps - their job is one of a kind.
They gave us a glimpse into a day in the life of a military working dog, starting from some doggy phys.
Dogs are either allowed to run free in a group or walked individually around the local area.
After their morning run around, it is on to their essential maintenance, with vet and dental visits at their on-site veterinary hospital.
The veterinary surgery is open to civilian and military animals, treating a lot of the BFG pet population.
It's fully equipped to deal with everything from simple check-ups to more complicated operations.
After a busy morning chasing tails, it is time for lunch, which is weighed and measured to the gram, and individual to each dog.
Agility training increases the dog's balance and helps to work on their physical control and stability, while bumper training gets the dogs listening to the handler.
As well as physicality, they also focus on the dogs most powerful sense – that of smell, including training to find a piece of IED just a few millimetres wide.
The regiment plays a vital role in not just IED detection and building or vehicle searches, but also in protection.
After a hard day showing intruders who’s boss, there is only one way to cool down - the regimental padding pool and lake.
This will be the last German summer for these hard-working military pooches though, as they will soon rebase to North Luffenham in the UK.
