On a pair of canoe trips this past fall, it was clear that my dog was uncomfortably cold. I ended up wrapping her in my rain jacket as we floated one river in October, but that was still far from ideal. I wish I had Ruffwear’s K-9 overcoat, an insulated dog coat that handles cold weather well, as it has done this winter. It keeps her warm without restricting her movements. She hasn’t tried to take it off. The shell is made of 100 percent recycled fabric and is abrasion- and snag-resistant. It is lined with fleece, though the fleece showing here is actually Ruffwear’s Climate Changer fleece sweater (not included). The coat retails for $64.95. www.ruffwear.com — Javier Serna
