Officers are appealing to trace the owners of a dog seen worrying sheep in Biddulph Moor.
The incident happened at around 11.50am on Tuesday 29 December in fields off Under the Hill.
The dog involved is described as a good sized black mongrel and is believed to be the same one involved in previous incidents at the location.
The sheep are all pregnant and this incident could have health implications for their lambs.
Anyone with information on the dog or its owners is asked to contact PC Clare Reynolds at Staffordshire Police on 101, quoting incident number 224 of December 29.
Dog owners are reminded to be vigilant when walking their dogs near livestock, always make sure it’s on a lead and under control. If using an extendable lead make sure you keep it short so the dog is by your side.
A dog doesn’t have to kill sheep, or even chase them, for its owner to be committing an offence. Letting a dog roam loose in an area where there are sheep can cause them stress and have health implications for their lambs.
Livestock are part of farmers’ livelihood and harm to them can cause them financial damage. In some circumstances farmers and livestock owners are entitled to shoot dogs that are loose amongst their animals.
