Can't let you get away with that. My dog can go out when its below freezing quite happily. I need 2 layers of clothing plus a coat.
Most dogs that can take the cold can't survive high heat. Likewise, dogs that can handle high heat usually do very poorly in the cold. With proper knowledge and acclimatization, a person can survive almost the same range as most dogs, and still a greater range than cold-adapted dogs. As for cold, I've heard stories about the Inuit. Some have come south for work, and found a few degrees C above freezing to be t-shirt weather and 10 degrees C above freezing is uncomfortably warm. Likewise, I've met people from the Caribbean who find a few degrees C above freezing to be winter jacket weather. With acclimatization, this doesn't matter. But I doubt your dog will do well in the Caribbean without some human assistance.
"We can survive bacteria, viruses and parasites and wounds"
So can most animals otherwise the most complex life would still be a sponge. And to use my dog as an example again - he can happily drink water from streams and puddles that would put me on the toilet for 2 days.
Which is pretty much exactly what he said:
We can survive bacteria, viruses and parasites and wounds. We die of infections beyond a certain magnitude, similarly to most other Eukaryote organisms. If our bodies are garbage, so are the bodies of all Eukaryote organisms.
Also, I don't think your dog is capable of boiling water, something we learned to do millenia ago thanks to our big brains. Evolution has given us a simple method to mitigate this problem.
Fact of the matter is, there are very few multi-celled organisms that can survive the temperature range that humans can stark naked. Add in clothing, and nothing at all matches our climate range. Yes, there are creatures that have greater extremes at either end, but they don't have the range we do, either.
