This is a camel-colored, size S dog sling released by RADICA (currently sold out). The purchase price was ¥4,690. I bought it in 2024 and only used it once (for about 30 minutes). I used it for a 2.0 kg Toy Poodle, but even the S size seemed roomier than expected, and he didn't seem comfortable, so I switched to something else quickly. I think the size would be suitable for slightly larger dogs, or for two smaller dogs. Both sides are mesh, providing excellent ventilation. It also has important features like a safety hook to prevent the dog from jumping out, a mesh lid, and wide shoulder straps. I think it's a product that covers all the important points.
