Mishnah Shabbat 5

¹With what may an animal go out [on Shabbat], and with what may it not go out? A camel may go out with a bit, a female camel with its nose-ring, a Libyan donkey with an iron bridle, a horse with its chain, and all chain-wearing animals may go out with their chains and be led by their chains. And they may sprinkle upon them [with purifying waters], and they may be immersed in their place. ²A donkey may go out with its saddle-cloth if it is tied to it. Rams may go out with hides tied to them. Ewes may go out with their tails tied up, tied down, or covered. Goats may go out [with their udders] tied up. Rabbi Yose forbids in all these cases, save ewes that are covered. Rabbi Judah says: goats may go out [with their udders] tied in order to dry them up, but not to save their milk. ³And with what may it not go out?A camel may not go out with a pad Or with forelegs bound together or with hind legs bound together; And the same is true for other animals. One should not tie camels together and pull [one of them]. But one may take the cords in his hand and pull [them] providing he does not twist them together. ⁴A donkey may not go out with a saddle-cloth, when it is not tied to it, or with a bell, even if it is plugged, or with a ladder[-shaped yoke] around its neck, or with a strap around its foot. Fowls may not go out with ribbons, or with straps on their legs. Rams may not go out with a wagon under their tails. Ewes may not go out with a hanun. A calf may not go out with a small yoke. Or a cow with the skin of a hedgehog, or with the strap between its horns. Rabbi Elazar ben Azariah’s cow used to go out with a strap between its horns, not with the approval of the rabbis.
