Primary Ciliary Dyskinesia

Body function:

Respiratory

Primary ciliary dyskinesia (PCD) affects the cilia, microscopic hair-like structures lining various body parts, including the respiratory tract. In dogs with PCD, the cilia are either malformed or immobile, leading to respiratory issues. This condition primarily affects breeds like the Old English Sheepdog, but it has been found in as many as 19 breeds.
