This dog backpack carrier is perfect for small and medium-sized dogs and cats, recommended for those under 20 pounds. Be sure to measure your pet's back length before purchasing and compare it with the dimensions of our backpack (see Fig. 3). The top features a drawstring design, allowing your pet to keep its head extended for ventilation and visibility, while the adjustable neck hole window also has a safety clip to connect to your pet's collar or harness. The backpack is made with breathable mesh and polyester fiber, as well as a thick sponge for added comfort. The sponge and solid bottom covers can be removed and washed, and the backpack also includes a built-in security leash, waist and chest buckles for extra support, and multiple pockets for storing essentials. Lightweight and portable, this backpack is perfect for outdoor adventures and can also serve as a fun photo prop. Our brand, GNISBIS, is dedicated to improving the quality of life for pets and their owners, and we take great care
