The ruling on one who is touched by a dog or whose clothes are touched by a dog

Question:
He says: The farm dog—may Allah prolong your life—when I bring it food, it may touch me, and it may touch my clothes. So, is it obligatory for me to change my clothes when it touches them? And is it obligatory for me to repeat the ablution? May Allah reward you with good.

Answer:
You do not have to repeat the ablution. However, if it touches something of your garment with its moisture, you wash the place where the moisture touched. As for if its skin touches your garment and it is dry, it does no harm. But if there is moisture: some of its urine, or its saliva, you wash what it touched seven times. What it touched on your foot, or your garment, you wash it seven times, and one of them should be with dust. It is better to have some dust in the first washing. Yes.

The presenter : May Allah reward you with good, and may He do you good.
