Pets are not allowed in cars without the host’s explicit consent except in the case of service animals. For information on what constitutes a service animal (in the US only), check out that information here. We strongly recommend that all guests notify their hosts ahead of time that a pet will be present for the trip, even if it’s a service animal, as hosts may request reimbursement for cleaning.
If a host reports that a guest has transported a pet without the host’s authorization or the car is returned significantly dirtier than when it was picked up, the guest will be subject to additional fees and may have their membership revoked for violating the Terms of Service.
