My wife seems to think our Lab needs a winter jacket to wear outside in cold weather. We live in NC, so it doesn’t get very cold here and it rarely snows. I take Dooley on long walks and hikes nearly every morning in temperatures ranging from 30s to the 60s, and she doesn’t seem cold to me. She gets friskier in cold temperatures but doesn’t shiver or want to stay inside. She’ll jump in the nearest creek or pond no matter the temperatures. Should I just humor my wife and let her buy Dooley a fleece jacket for the cold, or would this just be a waste of money or actually make her colder?
