بِسْمِ اللّٰهِ الرَّحْمٰنِ الرَّحِيْمِ
“In the name of Allah the Most Gracious, the Most Merciful.”
-The body of a dog is not considered as impure, however it’s saliva is. Therefore if the saliva of a dog gets onto the body or clothes wudhu will not break however, one will have to wash that part of the body or clothes as they would if any other impurity got on to it. (see details under general purity)
-If a suckling child vomits a mouthful (which is usually the case) that part of the body & clothes will have to be washed. If it less than a mouthful, salaah can be performed without washing it, but it will be makhrooh (disliked).
