The victim was staying at a holiday cottage near to Williams’s racehorse training centre.
He took his cockerpoo Gulliver for a walk in a paddock that was part of the stables, and because it was dark was using a torch.
There had been incidents of fly-grazing on Williams’s property in the past – where animals are left on land without permission – as well as hare coursing and poaching.
His family spotted the lights on their land and believed Dandridge was “lamping”, when people use bright lights to find animals such as rabbits and foxes, often with a dog.
When Williams arrived the lights began moving towards him and he became aware there a person and a dog.
Approaching the man, Williams told the jury he shouted at him to put out his light as he was worried it would upset his horses.
“The light would have been flickering in the stables and that can trigger horses,” Williams said.
He wanted to get control of the man’s dog and was “trying to grab his extendable lead”.
