What is tracheal collapse?
Tracheal collapse is a common cause of coughing and airway obstruction in dogs. The trachea, which is also known as the “windpipe”, provides the air supply from the outside to the lungs. The trachea can be thought of as resembling a vacuum cleaner pipe. It is a flexible but firm tube that is reinforced by strong cartilage rings. These rings are not complete but rather “c-shaped”, with the open end of the “c” facing to the inside of the neck with a ligament attaching from the one end of the C to the other. Sometimes these cartilage rings weaken and cannot hold their shape causing the trachea to narrow or even close, making it more difficult for air to pass through.
