A pet transporter that can be towed behind a wheeled vehicle is disclosed. The pet transporter comprises a carrier member, a frame adapted to receive the carrier member, a pair of side bows attached to the side walls of the carrier and to the frame, a pair of wheel assemblies attached to the frame on opposite sides of the carrier, and an attachment arm with a first end and a second end, wherein the first end is adapted to be attached to the frame proximate the front wall of the carrier and the second end is adapted to releasably attach to a rear axle of a wheeled vehicle. The pet transporter has a low center of gravity, making tipping of the pet transporter more difficult. In addition, few tools are required to assemble and disassemble the pet transporter.
