Yea I got a fleece coat for reef too it seems to help. I have a boston terrier i need to put a sweater and a coat on him just to go outside in cold weather or he wont even go sometimes lol. my pure breed heeler was fine last weekend temps were 30 at night I pitched an oes tarp for them and had a blue tarp on the ground and a few blankets my pure breed heeler Brody slept outside the tarp with no blankets reef however was wrapped in a fleece blanket with me in the hammock then I used my sleeping bag to cover us both up as a tq he stayed really warm and kept me much warmer
