Puppies join Police Scotland as latest recruits to force Two new puppies have been recruited to join Police Scotland's crack team of canine crime busters. Brother and sister Trio and Buster are being trained up to become members of the force's dog unit. The nine-week-old cocker spaniels were specially selected because of their pedigree and the achievements of their family. For the first year of their life both Buddy and Trio will be looked after, and trained, by dedicated Police Scotland dog unit instructors. They will live with their instructor, but work at the Dog Unit at Pollok Park in Glasgow. Trainers want them to get used to lots of different environments and surroundings, and will be meeting the public, walking around buildings and trying out different forms of transport. Their tough schedule currently involves playing fetch with a tennis ball up to four times a day, followed by a restorative nap. As they get older, the training will build up accordingly, and different obstacles and scents will be introduced. If they impress during the first year, they will join a more intense training programme, and could eventually be used to sniff our explosives, cash or drugs, or even seek out victims of a crime.
