Yet it turns out the risk almost wasn’t worth taking.

One afternoon Charlotte was playing in the garden with Khan while Catherine watched on from the house. Khan had been with the family for just four days.

All of a sudden Khan changed. He was crazy, angry and uncontrollable. He went up to Charlotte and knocked her straight onto the ground.

Something had spooked Khan. He was possessed and snarling.

Charlotte and Khan had seemed to get a long, but the dog was about to do something that the family would never ever forget.
