dogs
I would advise you to go with some type of wirehaired dog if you want a pointing dog. Or a Cheasapeake bay retriever if you want a retriever. Cheasapeakes love the cold, they have gotten a bad rap about there temperment. Mine is great with people and other dogs.
My pointers do just fine in South Dakota every year. Sure they are a little cold to begin with, but once they get to moving they are fine. Daytime temps are anywhere from -20 F to 30 F. I put a neoprene vest on them and they are great.
