I'm selling this because I didn't end up using it. Hopefully, someone who will can! I think it's a roomy size for a 5kg Chihuahua. [Pet Carrier Bag] This shoulder-type carrier bag for small dogs and cats was developed with various uses in mind, allowing for use anytime. Based on surveys, this carrier bag was developed with features such as use on public transportation, stability and peace of mind, design, comfortable space, convenience in case of disasters, durability, storage capacity, and stability of the bottom board. [Ease of Use and Stability] By attaching the anti-escape lead inside the bag to the collar, your dog won't jump out even when the window is open, giving them a sense of freedom. [Expandable House Function] You can expand it into a mesh house by opening the side zippers. It also has an entrance, so it can be used as a pet house indoors. Also, opening the side of the bag and the entrance of the expansion part creates two entrances, making it a new carrier bag that can be a play area for cats as well as dogs. [Active in Transportation] When not in use, the carrier bag can be folded compactly and doesn't take up much storage space. Also, you generally can't see inside from the outside, so you can travel with peace of mind on public transportation. In addition, the side of the bag has a sleeve for a carry-on case handle, making it easy to move around even when traveling with a lot of luggage. ★Even if it's a new, unused item, there are some items that have been opened once for photography or to check the contents.
