Although if you are in the middle of nothing, you will rarely encounter problems.
Mari had a Finnish Hunting dog (you know the ginger ones with a curly tail) that lived outside 365 days a year. Quite as happy in -30 (centigrade)as it was in +30 (or, at least as happy as the rest of us) It was about 18 when it died last year. Out here in the sticks, in fact, almost everyone I know has dogs that live outside. Mostly hunting dogs.
Cats live inside, dogs are just workers

Peter's right, the vet is also pretty expensive, and if your pooches are used to Florida, then they might have a bit of a shock in the Finnish winter.
We're really not trying to be negative here, it's just better if you know the reality now
