We used this for my 8-lb yorkie poo to travel across the country on the airplane. She usually HATES the pet taxi, but she LOVES this! Its soft and SO versatile! We could carry it as a backpack, roll it in the airport, use it as a tote..just amazing! Our yorkie poo did freak out a little bit, as it was her first time in the airport and tried biting at the zippers--and NO DAMAGE! She has literally eaten zippers before on other carriers, so this one is VERY durable! HIGHLY RECOMMEND!
