CITYDOG backpack carrier bag made with breathable mesh material. Size is R. Used about twice, but it was too small for my dog (3.5kg), so I am selling it. [Citydog] Neoprene Backpack Carrier Color: Moca Size: R (W31.5 x D19 x H38cm, under 5kg) Citydog's washable dog carrier. Made of neoprene, so it can be washed when dirty, and it's also very light, so I recommend it. *Will be folded slightly for shipping. - Brand: CITYDOG - Color: Moca - Style: Backpack - Material: Mesh, Nylon Thank you for looking.
