Dog owners have been warned to keep their pet on a short leash while walking in the hills this summer.

From sheep covering the Ochil Hills to ground-nesting birds hidden in the heather of the Trossachs, summer is breeding season and even the friendliest of dogs can have a devastating effect on wildlife.

Police in Forth Valley pointed out that under the Scottish Outdoor Access Code, dogs must be kept under close control around livestock, as a chased sheep can die of shock or miscarry a lamb.

Cows can turn aggressive if they feel their calves or themselves are threatened. If a cow approaches, dog owners have been encouraged to let their pet off the lead so they both can escape.

It’s also recommended that dog walkers and hill walkers stick to a trail as ground-nesting birds camouflage their eggs on the land, and by wandering off course, walkers can crush a nest.
