Calm, hardy, well adapted to high-mountain conditions. Less aggressive compared to average indicators for the species, has a strong herd instinct, resistant to cold and rarefied air.
Arunachali yak — compact, short-legged, very sturdy breeding line of the domestic yak, adapted to the humid monsoon climate of the Eastern Himalayas (3000–5000 m). Differs from other Indian and Chinese yaks by a smaller head, shorter muzzle, significantly thicker and longer coat on the lower neck, chest and sides, compact barrel-shaped body, short tail with a dense "brush". Height at withers: bulls 120–135 cm, cows 105–118 cm. Live weight: bulls 280–420 kg, cows 180–260 kg. Body length: bulls 190–240 cm, cows 170–205 cm. Dominant color — deep black or black-brown; silver hairs on the croup and tail ("silver tail"), light markings on the belly are allowed. Compactness index 0.55–0.60, chest girth / height at withers > 1.45. Not allowed: long legs, narrow chest, light color on more than 10% of the body surface, weak coat.
