A dog owner has told a passer-by that everything will be okay because Rex doesn’t bite.

“It’s all good, Rex won’t bite,” said dog owner Mary Pratt.

“He’s such a good boy, he wouldn’t hurt a fly,” Pratt said while mustering up all her strength to keep some control of the leash.

Pratt dragged the “friendly”, “mild mannered” beast across the road to the other footpath.

Rex, who “just wanted to play”, murdered another two flies on his back way home.
