Myotonic (Fainting) Goat

Capra hircus · also called Fainting Goat, Tennessee Fainting Goat, Wooden Leg Goat, Stiff-Legged Goat, Nervous Goat, Texas Wooden Leg

⚖️ Compare

A stocky American meat/homestead breed famous for myotonia congenita, a harmless muscle condition that makes the goat stiffen and sometimes topple over when startled. Calm, easy-keeping and increasingly popular as a pet and brush-clearing animal.

Habitat & space requirements

From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum

Pair + browse paddock + shed

0.25 ac paddock for 2 head + 3-sided shed + climb area

Meat goats are still herd animals — keep at least 2. Paddock with browse, climbing logs/rocks, a 3-sided shed, hay, minerals (copper + selenium where deficient), and a 5 ft tight-bottom fence.

Recommended

Rotated browse pasture

≈ 0.5 ac per goat, rotated paddocks

Rotate paddocks across varied browse to manage parasites and forage. Provide free-choice minerals, clean water, a shelter/windbreak, and an LGD or strong perimeter fence against coyotes and stray dogs.

Ideal

Pasture + browse + barn

Managed rotation, barn, separate buck pen

Mixed pasture and browse with climbing terrain, a kidding barn, and a separate buck pen. Hoof trimming every 6–8 weeks, parasite monitoring, and routine vet/breed health checks. Myotonic ("fainting") goats stiffen briefly when startled — fencing should be doubly secure and pasture mates calm; otherwise standard meat-goat care.

Life & growth stages

How this animal changes through its life — each stage often has its own care, diet and space needs.

Newborn

Newborn mammals are nursed on their mother's milk. Many are born helpless — blind, deaf, and sparsely furred (altricial, as in dogs, cats, and rodents) — while others stand and follow within hours (precocial, as in hoofed livestock).

Photo coming soon
Juvenile

After weaning, juveniles grow quickly and become increasingly active, playful, and independent. Adult coat, proportions, and (in many species) the permanent teeth come in as they approach full size.

Adult

Adults reach full body size and sexual maturity, with the species' mature coat and build. Sexual dimorphism — differences in size, mane, horns, or markings — is pronounced in some mammals and subtle in others.

Photo coming soon
Senior

Senior animals show aging signs such as graying fur, reduced activity, and a greater need for veterinary monitoring of joints, teeth, and organ function. Lifespan and the onset of old age vary widely by species and size.

Color & pattern variants

Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.

Selectively bred (man-made)
Standard Myotonic

Standard Myotonic

The full-size meat/homestead type registered by myotonic goat associations; any color and markings are accepted, with black-and-white being common.

Miniature / Mini Myotonic

Smaller lines selected for reduced height, kept mainly as pets and for small homesteads.

Habitat & enclosure

Pasture with a draft-free three-sided shelter or simple barn; a secure perimeter fence (woven wire 4 ft / 1.2 m). Because they stiffen and fall when startled, they are poor escape artists and easy to contain, but for the same reason they are vulnerable to predators and to falling on hazards — keep ponds, steep banks and tall feeders out of paddocks. Provide dry bedding, shade and ~200+ sq ft (20 m2) of turnout per goat plus low climbing platforms.

Diet

Browse and good-quality grass/legume hay as the base; pasture and brush are eagerly worked. Free-choice fresh water, loose goat mineral with copper and selenium, and salt. Grain only for pregnant/lactating does or thin animals. Avoid sudden ration changes; their well-muscled but easy-keeping build means many wethers and pets get obese on grain.

Behavior & temperament

Docile, quiet, friendly and less inclined to climb or jump than most breeds — an asset for fencing and family settings. Originally a meat goat (high muscle-to-bone ratio, two breedings per year possible), now widely kept as pets, show stock, brush clearers and as a heritage conservation breed. The myotonia is not fainting or loss of consciousness: a startle reflex causes temporary muscle stiffness (seconds to ~10-20 s) and the animal stays fully awake; severity varies and many habituate to handlers.

Health

Generally hardy with few breed-specific diseases; the myotonia congenita is benign and not painful. Welfare notes: startle-induced stiffening means they can fall and bruise or be injured, are easily caught by dogs/predators, and stressful handling should be minimized. Otherwise prone to the usual caprine concerns — barber pole worm (Haemonchus) and other GI parasites, coccidiosis in kids, hoof rot/overgrowth, and copper/selenium deficiency in deficient soils. Listed as a heritage/recovering breed.

Tips, DIY & hacks

Don't deliberately startle them for amusement — repeated stress is poor welfare and they brace rather than relax over time. Trim hooves every 6-8 weeks and do regular FAMACHA eyelid checks for anemia from worms. Their easy containment makes them ideal first goats; pair with at least one companion goat (never keep singly). Choose a shelter and paddock free of drop-offs and hard edges so a stiffening episode can't cause injury.
