I live on the 30th parallel so we get temps anywhere from 0 to 110 generally. I have a friend who has two dobermans and a husky and he puts booties on the dogs when it snows and it works pretty well. I've seen sweaters on the dogs also, but I don't know if that's just because they wanted to dress them up. Dobies have similar coats and if that is why our Boxers have cold issues, the sweater should work for our dogs too. Plus they can get dressed up for the holidays!
