A fence that has to resist the goats as well as the predators
Nubians test fencing from the inside harder than many predators test it from the outside. These are tall dairy goats with long legs and a habit of rearing up, planting their front feet on the mesh, and surveying the world — and a fence that flexes under that treatment soon sags into footholds a coyote can climb and gaps a dog can force. Start with woven wire in a heavier gauge than you would use for sheep, on posts set close enough that the line stays drum-tight between braced corners.
Small openings low on the mesh still matter: Nubian kids are leggy rather than tiny, but a kid that gets its head through woven wire and panics can be injured or stuck, and the noise of a trapped kid at the fence line is a dinner bell.
Inside wire, outside wire: two different jobs
An electric strand earns its place on both faces of a Nubian fence, doing different work on each side. On the inside, a strand at goat shoulder height teaches the herd to respect the mesh instead of leaning, rubbing, and standing on it, which is what preserves the fence's strength for the years ahead. On the outside, an offset strand set away from the posts meets a dog or coyote before its teeth or paws reach the woven wire.
Neither strand helps if it is shorted out. Nubians will push browse and branches against the line, so walk it with clippers and clear anything leaning on the wire, especially after wind. Test the offset strand at its farthest point from the charger, not beside the barn where it always reads strongest.
Gates a Nubian cannot operate
Goats in general work latches with lips and persistence, and a gate that drifts open does a predator's job for it. Hang mesh-filled gates rather than barred ones, fit them with latches that need a deliberate lift-and-pull, and back the latch up with a chain or clip if the herd has an escape artist. The gap under the gate should match the fence's ground line — a long-legged kid cannot use it, but a digging dog will try, so a threshold board or a buried mesh skirt under the gate line is worth the work.
Shelter placement matters too. A Nubian standing on a shelter roof or a hay ring beside the fence has quietly added the height she needs to go over, and a frightened herd following her out is exposed exactly when predators are active.
Seasonal checks for a strong, busy herd
Recheck tension after the ground freezes and thaws, after any tree comes down near the line, and whenever you move the herd to a new paddock — the first day in fresh ground is when Nubians push hardest on an unfamiliar boundary. Look at post bases for the soft, dug look that says something has been working there at night, and fill and compact any start of a dig immediately.
A goat found with puncture wounds, a limp, or torn skin after a night of herd noise should see a veterinarian promptly, even if she is eating — wounds under a dairy goat's jaw and brisket are easy to underestimate.
