what female goat has 4 working teats?

A female goat with four working teats is often referred to as a "dairy goat." While most goats typically have two functional teats, certain breeds, such as the Nigerian Dwarf or the Miniature Nubian, can exhibit this trait. These additional teats may not always produce milk effectively, but they can still be functional. Breeders sometimes select for this trait to enhance milk production.
