It might seem counterintuitive, but snuggling up to one's dog in a traditional sleeping bag can actually make both parties involved colder at night due to compressed insulation; the Barker Bag by Andy Storms, a designer based in Seattle, Washington, remedies that situation. It provides a small sleeping bag attachment for canine companions.
Shaped like a teardrop, the Barker Bag by Andy Storms is ideal for connecting to the side of one sleeping bag or between two bags. This connection allows the sleepers to share their body heat instead of taking away from it. It even comes with a built-in dog collar so that their furry heads are not obstructed throughout the night. They are excellent night lookouts after all. The collar is adjustable to make their rest as comfortable as possible.
