I live in Northwest British Columbia in Canada and we have been having lots of rain the past few days and right now were sitting at 8 degrees Celcius. Mabel is 18 weeks and 2 pounds and seems to start shivering before we get out the door. I made her a little fleece sweater and put her harness over top of the harness. She's not thrilled but she gets outside and does her business pretty fast. I can't wait for her to see snow!!
