A Wool Breed With a Lambing Calendar That Changes the Risk
Dorsets are medium-sized white wool sheep valued because ewes can breed and lamb outside the usual spring window. That flexibility spreads your lambing across more of the year, which also spreads the weeks when tiny, slow lambs are on the ground and most attractive to coyotes and stray dogs. Fencing for Dorsets therefore has two jobs: a sound pasture perimeter for the flock day to day, and a genuinely tight night pen for the lambing groups.
A single large field fence, however well built, rarely does the second job well. Distance from the barn, unlit corners, and long grass all work in a predator's favour after dark.
Pasture Perimeter for the Main Flock
Start with woven wire rather than widely spaced strands, choosing mesh small enough at the bottom that a lamb cannot push through and a dog cannot get purchase to climb. Tension it between well-braced corners and keep the bottom edge following the ground into every hollow, because Dorsets graze low ground thoroughly and will find, then widen, any place the wire lifts.
Where soil is sandy or dogs have dug before, turn the bottom of the mesh outward into a ground apron or bury that edge, so digging meets wire instead of open earth. An electrified strand on offset insulators outside the mesh, at the height a coyote carries its nose, adds the psychological barrier: the shock arrives before claws ever touch the woven wire.
The Night Pen Is the Dorset Difference
Build the lambing and night pen as a smaller ring of your best fencing, close to light, people, and the barn. Use finer mesh here, a gate that closes flush with no climbable gap beneath it, and enough height that a determined dog cannot clear it from a running start off a bank or woodpile — so keep anything stackable away from the pen's outside.
Penning ewes with young lambs at dusk and turning them out after a morning check is labour, but it removes the hours when Dorsets are most vulnerable and when a problem in the big pasture would go unseen until morning.
Reading the Signs Along the Line
Wool tells stories. Tufts caught on wire at one height suggest sheep pushing; tufts and scuffed earth low down suggest something testing from outside. Check water trough corners and gate hinges, watch for lambs sleeping tight against the fence, and note any ewe who starts lambing in the far field rather than the pen — she is telling you the routine slipped.
When a predator does breach a pen, secure the survivors first, photograph the entry point before repairing it, and adjust that exact weakness rather than rebuilding everywhere at once.
Because Dorsets may be lambing when other flocks are not, keep a simple record of which group is in which pen each week, and match your strongest pen to the youngest lambs rather than to whichever group is easiest to move. A ewe a few days from lambing who is moved early settles; one moved in a hurry after trouble starts may lamb in the pen gateway instead. Planning the pen rotation a week ahead, around expected lambing dates, keeps the tightest fencing wrapped around the lambs who need it most, in every season this breed chooses to produce them.
With KinsLe Care Teams, the dusk penning, dawn release, and perimeter walk for your Dorsets can be assigned by name and marked complete with a timestamp, so lambing-season chores never rely on memory.
