The carrier that does two jobs, and neither one feels like a compromise.

The K9 Sport Sack Urban 3 is designed for owners who do not want to choose between their dog and their daily routine. It functions as a fully capable human backpack - padded laptop sleeve, expandable side pockets, waist support strap, sternum strap and a contoured back panel - and converts seamlessly into a dog carrier when needed. Whether you are commuting, travelling light or heading out for the day, it handles both roles without looking like either one is an afterthought.

The dog compartment sits at the rear of the pack, with leg openings that allow a natural, supported riding position rather than forcing your dog to hunch or perch awkwardly. A dual cinching collar enclosure and carabiner safety clip keep them secure, while side zip ventilation keeps air moving on warmer outings. MOLLE webbing loops on the front and back let you clip additional accessories as needed.

K9 Sport Sack carriers are developed with veterinarians, animal behaviour specialists, dog trainers and veterinary chiropractors. Every model is reviewed by a vet before release. Your dog's spinal health and long-term comfort are part of the design brief, not an afterthought.
