When the frost settles on the yard, your canine coworker doesn't get to punch out early. Gear them up for all of their perimeter patrols with a rugged denim jacket built with the same grit of your own favorite work coat. Stuffed with lightweight insulation and lined with thick, plush sherpa fleece, this denim shield blocks out the bitter cold. Best of all, a clever center-back welt lets you snap a leash onto their harness without letting a single lick of warmth escape.
