They don't have any teeth on their top jaw, only a dental pad.At approximately one year of age, the central pair of baby teeth is replaced by a pair of permanent incisors. At age 2, the second pair is replaced by permanent incisors. At 3 and 4 years, the third and fourth pairs of baby teeth are replaced. There are also different names for sheeps. They are,

In 1930, they were described as large sheep without horns, dark faces and legs, fine bones and long small necks. They were low set in front with high shoulders and light forequarters; however, their sides were good, rather broad in the loin, and were full in the thigh and twist.
