Does the presence of a female dog and a woman in the same dwelling affect the validity of prayer and fasting in Ramadan?

Your prayers, fasting, and acts of worship are valid and are not affected by the presence of a dog or a woman. However, your living alone with a woman is a gateway to great tribulation and evil, so it is not permissible for you to live alone with her. If there are others with you both and you do not fear tribulation, then there is no harm. But if you fear tribulation, then you must seek a place far away from her.
