This 2-in-1 dog trailer switches from a bike-towed trailer to a walking stroller, sized for dogs up to an 88-pound weight limit inside a 31.5 x 21 x 20.8-inch compartment. A height-adjustable push handle extends from 30.9 inches at a 90-degree angle to 44.9 inches at a 180-degree angle, letting taller or shorter handlers find a comfortable grip when using stroller mode. The frame is powder-coated steel wrapped in waterproof, sunproof 600D Oxford fabric that holds up to sun and rain. Up front, a zippered mesh layer paired with a PVC canvas panel lets you open the door for a breeze or close it to keep your dog dry, and both front and rear zippered doors make getting your pet in and out simple. The coupler attaches to bikes with 22 to 28-inch wheels for a quick connection, and the whole unit folds down to 31.5 x 22.4 x 7.7 inches for storage when not in use. At 32.19 pounds, it's easy enough to carry folded between trips, whether you're heading out for a ride or a walk around the block.
