K9 Sport Sack AIR PLUS Forward Facing Backpack Dog Carrier

This item available in store only
Don't leave your best pup behind! Your dog can ride in comfort and safety in this backpack dog carrier. Perfect for taking small to medium sized dogs along on moderate hikes, bike rides, public transport, or just a nice long walk in the sunshine!


The AIR PLUS is a pet carrier built by you! The design is based on years of research and feedback from thousands of loyal customers. With additional storage, padding and ventilation the AIR PLUS is built for intermediate hikes, bike rides or any moderate outing you can dream up. Like all K9 Sport Sack models, it was designed under the close direction of veterinarians, dog trainers and outdoor product engineers to be ergonomic, safe, and strong. 40 LB/18 KG weight limit.

**All dogs are unique! If your dog is between sizes or still growing, we have booster blocks available for these backpacks to give them up to a 3 inch (or up to 6 inches with two blocks) boost for a more comfy ride. Add a booster block here.
