They are being prompted to guarantee their animals are under control on a lead whenever they are near animals – which the offense can call for a prison term or a fine of approximately £1,000.
A Dorset Police representative said: “Livestock stressing is a criminal offense under the Protection of Livestock Act 1953 and does not need an animal to be hurt.
“Allowing a dog to be off a lead or otherwise not under close control in a field or enclosure of sheep is an offense.
“The charge for animals stressing can be 6 months’ jail time and/or a fine of approximately £1,000.
“We wish to advise all dog owners to guarantee their dog is on a lead whenever it is near animals.”
