Capacities vary widely; examples in this selection include carriers rated for 66 lb, 100 lb, 160 lb, and up to 300 lb.
Many carriers combine mesh panels or zippered mesh doors for airflow with PVC or polyester exterior panels for rain and wind protection. Some models also include transparent PVC flaps to maintain visibility while shielding pets from the elements.
Many models fold or collapse for compact storage, feature quick‑release or removable wheels, and use one‑click or latch folding mechanisms to simplify transport and stowing.
Many wheeled crates include removable plastic or slide‑out trays that are leak‑resistant and make cleaning faster and easier.
Most listings note adult assembly is required (tools provided). Common included components are the frame or carriage body, wheels or caster wheels, removable trays or pads, and assembly hardware.
