The Ruffwear Approach pack turns a conditioned adult dog into a helpful trail partner: padded harness chassis, side saddlebags, and enough capacity for dog water, a collapsible bowl, and light extras.
Keep total loaded weight at or under about 25% of body weight, start with empty-pack conditioning walks, and skip packs entirely for puppies whose growth plates are still open.
Balance both bags so the pack does not torque the spine on uneven trail.
