http://www.aaha.org/blog/NewStat/po...-to-the-bottom-of-border-collie-collapse.aspxBorder Collie Collapse, or BCC, is recognized as a form of exercise intolerance in Border collies, Kelpies, and related breeds in the United States, Canada, and Australia. Dogs with BCC are normal at rest, but after 5–15 minutes of strenuous exercise can develop incoordination and altered mentation. Recently, JAAHA posted an exercise study on dogs with BCC in issue 52.5 and a survey on observations of dogs with BCC in issue 52.6.
While many veterinarians and dog owners have not heard of BCC, Sue Taylor, DVM, DACVIM, lead researcher on the BCC study printed in JAAHA, said, “It is not rare and is a significant problem in the breed.” Organizations like the American Border Collie Association, the AKC Canine Health Foundation, and the Border Collie Society of America have all recognized this and supported Dr. Taylor’s research.
BCC may be a significant problem, but there is no data on exactly how prevalent it is, because a diagnostic test that can confirm it does not yet exist. Katie Minor, BS, one of the researchers involved in the study, discussed attending a large stock dog trial in Minnesota, where the owner-reported frequency of BCC in dogs there was about 5%. If this percentage is indicative of its presence across the breed, BCC is about as prevalent as the exercise induced collapse (EIC) issue in Labrador retrievers, but researchers have to find the source of BCC to more accurately determine the numbers.
Thought it was interesting as it sounds so familiar. @Ben Howell , worth highlighting to Ron?
