Scores of children and grown-ups wrote to Police-Constable Ernie Pugh, 27 when they heard, two weeks ago, that his police dog pal Rajah had been shot through the shoulder in an encounter with a gunman. Now Rajah, seen here with Police-Constable Pugh at Bayford, Herts, yesterday, is back on duty and as fearless and obedient as ever. It was feared that the injury he received when he tackled the gunman after a burglary at Brookman's Park, Herts, would make him either too timid or too vicious to be a tracker again - for the encounter was his first with a criminal. But, in a try-out yesterday, he "got his man" and held on until Police-Constable Pugh arrived to make the "arrest". March 31, 1952.
