|Exercise Induced Collapse (EIC)|
EIC is an inherited disease found in Labs and other breeds such as Curly-Coated and Chesapeake Bay Retrievers, Cocker Spaniels and Pembroke Welsh Corgis and more. Affected dogs typically become weak in the hind limbs and collapse after 5-20 minutes of high intensity exercise, such as in field trials or upland game hunting, and in some cases simple fetch and retrieves.
University of Minnesota's Veterinary Diagnostic Laboratory website has extensive information on EIC, DNA testing and a video of the collapse.
