Mixing of impure clothes with pure

Question ID: 38953

I am from Malaysia. Last week me and my family went for trekking in Nepal, there were so many friendly dogs there and my wife seems to feel doubt, and now she confirmed that one of the dogs with a wet nose has touched her trousers.
But back in Malaysia, she forgot to separate that trouser and washed it in a washing machine together with all other clothes.
Do we need to clean all other clothes with soils too?
If yes, does that mean I need to clean all the clothes by hand? or I just treat all the clothes as one?

If you clean by hand it is very good.
