TRAINING CARRIER – Designed with a minimal frame & breathable mesh siding, the Trainer is the perfect way to introduce your small dog and/or puppy to backpacks. It will fit most comfortably on dog owners with small to medium builds.
FIND THE RIGHT SIZE – The X-Small is best for dogs with a length of 9-12” from collar to the base of the tail. Typical dog breeds that will fit this size backpack include Chihuahua, Havanese, Pug, Shih Tzu, Yorkshire Terrier & Toy Poodles.
FOR CASUAL, SHORT-TERM USE – In addition to early-stage training, this carrier is great for quick, everyday outings when walking them doesn’t work—commuting, cycling, vet trips, a quick walk on hot pavement, or maybe just when they get tired.
SAFETY – Even though it’s only a temporary solution, the Trainer still comes with all our standard safety features, so you can count on the quality & peace of mind you enjoy with any other K9 Sport Sack purchase.
COMFORT & MOBILITY – This ultra-lightweight backpack features a simplified design that ensures easy on/off use, an ergonomic structure to promote weight distribution, ventilated side panels, a lumbar support strap, and padded shoulder straps.
