Britain's longest serving police pooch has retired from a successful career of busting drugs gangs to spend more time chasing tennis balls. Brewster, an English Springer Spaniel, served for nearly 11 years on the beat as the Bedfordshire, Cambridgeshire and Hertfordshire Dog Unit’s longest serving drugs, cash and weapons dog. The 13-year-old brown and white canine, 91 in dog years, was the companion of PC Dave Pert.
