In a -50°F blizzard, how to generate enough body heat to avoid frostbite?

The Winter is coming soon (in ~3 months) here in North Dakota and I’d like to be better prepared than last winter. I have hit a weird personal threshold [mere 5 degrees] that I cannot seem to comprehend: I can walk outside comfortably even at -42°F (-41 C) blizzard but when it was -47°F (-44 C), it was brutal and my hands were getting frostnip just after 20 minutes, despite having thick, heavy, large mittens.
I was wading through almost knee-deep snow, which at -25°F (-32 C) means I would be unzipping layers, as it’s simply too hot. But not at -47°F (-44 C). Now, the air itself was quite warm – around -35 (-37 C), which without wind is [obviously] perfectly fine and comfortable.

But the snow particles were like thousand needles biting into my face (I only had a regular hat with ear flaps that can be closed via clips, no facemask or anything). Even my Siberian Husky seems to have hit her limit – every single blizzard (including the -42°F (-41 C) a week ago), she waltzes happily against the wind. This time, after 5 tries, she turned her back and just let the wind push her.It was too much for a Husky.

There is a possibility that the interpolated data at the weather app were incorrect, as I talked next week to a friend who lived 30 miles NW and they got around -65°F (-54 C) windchill.

Given the fact that we have sometimes 3 storms in a week and I need to walk my Husky 4-5 times a day, I cannot avoid the exposure and simply must go out even when infrastructure everywhere around shuts down for a week.

Example – there was one week last winter, where every single time I went out (4-5x a day), there was a storm (I managed to sleep through the quiet times and "save" my walks for blizzards/storms).

So, what can I do to make the half-hour trip outside less miserable and more safe? Also, I’m pretty sure I am not equipped for -65°F (-54 C)…
