These packs are designed to fit the contours of your dog. They give your pet the capacity to carry a load in comfort without the pack interfering with your dog’s stride. They can be easily adjusted for a perfect fit. The bombproof construction will hold up to the rigors dogs can dish out. Fleece lines the sides that come in contact with the fur. Tubular nylon webbing, with its softer rolled edges, won’t cut into the skin. Fasten around the front and under the belly for a secure fit.
