No, they will not be okay. They are not built for the cold weather. Bring them in until you can get heated doghouses if you house them outdoors. If they cannot be kept together, figure out a way to seperate them for a day or two.
If none of that is good enough, they need homes where they can be housed inside, or outside properly.
I don't know your situation ,but if it's anyway like when I was growing up then I feel as bad for you as your cold pets. It torn me apart when my parents would not get nothing but a doghouse and food for the dog. That's the only thing they would pay for. I felt awful when it was so hot outside or cold and I worried about them all the time. When I got older I realized I needed to give them away until I had a place of my own to keep them warm or cool. They didn't mean bad but it's the lack of knowing what the pets need. They are animals but they need things just like us.
Even though some dogs are outdoor dogs does not mean that they can handle any temperature that comes their way, be it unusually cold weather or a heat wave. In any extreme temps, hot or cold, even outside dogs should be brought in overnight during cold/daytime during heat wave. Put them in a crate, basement, small room, or leash them inside such as the kitchen area if you must (safely of course, with at least 6 feet of leash).
You never know,this person could really need your helpful and nice infomation. It's better safe and educate them then label judgement. Besides what if someone else got on and had the same question, they would feel attacked and dumb. Can't spread the word on how to treat pets like that. :)
