Yesterday it was horses and today it’s man’s best friend – dog’s. Our little book ‘One In For D & D’ lists more than five hundred slang words and phrases used by police officers in the West Midlands from the 1970s onward. The term ‘growler’ was an affectionate term for police dogs. They are trained for many different purposes but undoubtedly are known for ‘saving the day’ when officers are trying to deal with violent situations. It’s a foolish person who ignores the command ‘Stop or I will release the dog!’ The photographs are courtesy of Paul Richards and Andy Fidgett, as well as the BTP History Group. Some are featured in ‘Police Dog Heroes – the history of the BTP Dog Section’.
