Bearded Collie owners in the UK said that the most common health issues among living dogs were musculoskeletal—mostly arthritis and cruciate ligament rupture (CLR)—gastrointestinal (primarily colitis and diarrhea) and urologic diseases. Beardie owners in the US and Canada reported that the most common health problems were hypothyroidism, cancer, Addison's disease, arthritis and skin problems. Morbidity in the two studies is not easily compared, however; the UK report grouped diseases, while the USA/Canada report used more detailed conditions.
