The Granite Gear Long Howl is built a lot like your pack. It features an adjustable harness that keeps webbing straps off of your dog’s fur (where it can chafe) by way of wide, lightly padded straps. It’s lined with stretch-woven fabric—the same kind Granite Gear uses in people packs.
The removable saddlebags have reflective stripes so you can see Astro after sundown. “It hugged my 95-pound Lab’s barrel chest perfectly, and the kibble-stocked pack never got lopsided,” says our tester. $100-$200; 1 lb. 1 oz. (L); S-L; granitegear.com
