Hazrat Tawus once said that the passing of a dog breaks the prayer. Someone asked, does the passing of a woman also break it? He replied, no, they are a part of your own kind; they are your sisters and mothers.

Hazrat Bakr narrates that once during prayer, a puppy passed in front of Hazrat Ibn Umar (may Allah be pleased with them), so he repeated that rak‘ah.

Hazrat Ata says that the prayer is not invalidated by anything passing in front except a black dog and a menstruating woman.
