Ci the Border Collie has developed a fear of sheep making it impossible for him to perform his day job.
Instead of rounding up his flock, Ci is more likely to be seen being chased by it.
Mrs Lippington, 54, said Ci instinctively wants to work the sheep, but is too scared.
“If they run away from him, he will go after them and act like a proper sheepdog, but the moment they turn and face him he runs away.
“Sheep can be quite aggressive if they think they have the upper hand – they stamp their feet and gang up in numbers and act like an army.
“The only way to make it work is for me to get behind them first and shoo them so they run away and then Ci joins in. It just means a lot more work for us to do,” she added.
