Shabbos 5:4-6:1

Shabbos 5:4

A donkey may not go out on Shabbos with a cushion if it is not tied onto it. A donkey may not go out with a bell even if it is muted, nor with a yoke to keep it from turning its head to get at a wound [like a dog's cone], nor with a strap to keep its legs from rubbing together. Chickens may not go out with strings (to identify them), nor with straps on their legs (that keep them from jumping). Rams may not go out with wagons (that protected their tails) and ewes may not go out with a chip of wood in the nose. A calf may not go out with its yoke, nor a cow with a hedgehog's hide (to protect its udders), nor with a strap between its horns. Rabbi Elazar Ben Azariah's cow used to go out with a strap between its horns, counter to the position of the Sages. (Actually, it was his neighbor's cow but it's called by his name because he had the ability to object and didn't.)

Shabbos 6:1

A woman may not go out with threads of wool or linen, or ribbons in her hair, nor may she immerse in a mikvah with such things until they are sufficiently loosened to allow the water in. She may not go out with various types of decorative headgear if they are not sewn on to her hat (to prevent her from removing them in the public domain). She may not go out with a piece of jewelry called a "city of gold," nor with a necklace, rings - even one without a seal - or a needle without a hole (because they may come to be carried in the public domain). If she did go out with one of these types of jewelry, she would not be obligated in a sin offering (as the prohibition is rabbinic in origin).
