My dogs love this! It is large enough to carry both of them. They are 10 and 20 pounds. The steering is better with their weight in it otherwise it is a bit cattywampus. It was simple to put together and it easily converts from a trailer to a carriage. It is made of a quality canvas and my dogs seemed comfortable with the airflow. It does require a pillow or blanket or cushion for added comfort. But the bottom is very sturdy for the weight of my dogs so I had no problem with that.
