two pairs
an udder is an organ formed of the mammary glands of female four-legged mammals, particularly ruminants such as goats, sheep and deer. it is equivalent to the breast in primates. the udder is a single mass hanging beneath the animal, consisting of pairs of mammary glands with protruding teats. in cattle there are normally two pairs, in sheep, goats and deer there is one pair, and in some animals such as pigs and dogs there are many pairs. in animals with udders, the mammary glands develop on the milk line near the groin, and mammary glands that develop on the chest (such as in humans and apes) are generally referred to as breasts.

all the milk-secreting tissue leading to a single lactiferous duct is called a "simple mammary gland"; in a "complex mammary gland" all the simple mammary glands serve one nipple. humans normally have two complex mammary glands, one in each breast, and each complex mammary gland consists of 10–20 simple glands. the presence of more than two nipples is known as polythelia and the presence of more than two complex mammary glands as polymastia.
