The Dog Backpack Carrier in blue is perfect for adventures with your pet. Comfortable and secure, it's designed for both you and your dog. Size small! Fits toy poodles, mini Dachshund and cavalier King Charles up to 27lbs 13-17 inches. Light wear but in great condition!!! Zipper opening along the length of the bag for easier in and out. Adjustable straps for the user and adjustable straps to help more secure the pup at the top. Also has a clip at the top of opening. Finally can also fit a standard size 16oz water bottle. Use it for hikes, walks, public events, etc! I do not have the tag or original labeling, as shown in the picture, just used for reference on sizing for dogs/to see bag details.
