Accessories (sold separately): The wheel set consists of 2 directional front wheels with locking mechanism and two fixed rear wheels. Tools are required to attach the wheel set. The wheels are not included and must be ordered in addition to the kennel. Tips for training: Help your pet to get used to the carrier by introducing it gradually. Start
