Not true at all. How did dogs and cats survive prior to domestication by humans? How do feral dogs and cats survive? Untold generations of their ancestors survived without human assistance. What is cold to humans is not necessarily cold to pets. Pets should be protected from extremes but our temperature tolerances are not good representations of theirs.
They froze to death frequently
If they can’t reach shelter because they are tied too short or there isn’t any, then they are at the mercy of the weather just like someone locked out of their house in their pajamas.
We have farm animals that aren’t pets at all but they still have a way to get inside out of rain and snow, and food and unfrozen water. Animals have to be able to stay dry and get out of the wind.
the key is whether they can move around, go to the their dog house or get under the porch or other cover....
out dogs were never chained up...
on extremely cold nights, we let our dog into the garage...
our dog lived til almost age 18...and we live in the cold north...
Many domestic dogs are short haired. Not equipped to deal with frigid temps.
I have a Norbottenspets like this, and they love COLD but damn anyone who lets any dog die, like that!

That is true. But a dog chained up can’t always get to a place suitable to keep himself warm and watered.
