Exercise-Induced Collapse (EIC) in Chesapeake Bay Retrievers
Moderate Risk Category: Neurological Typical onset: 5 months - 3 years Hereditary: Yes Est. treatment cost: £100-£500 (management)
Exercise-Induced Collapse (EIC) can affect members of the breed within the Chesapeake Bay Retriever. Common indicators include collapse after intense exercise, hind limb weakness and incoordination during episode, and hyperthermia. EIC is a hereditary condition in Labrador Retrievers (and some related breeds) caused by a mutation in the dynamin-1 gene. Intense exercise causes episodes of collapse and incoordination, typically lasting 5-30 minutes, after which dogs fully recover. It typically becomes apparent at 5 months - 3 years. The large frame of the Chesapeake Bay Retriever can accelerate progression in weight-bearing conditions, making early diagnosis particularly valuable. This condition has a hereditary component — prospective owners should request documentation of health screening from the breeder. Treatment costs are estimated at £100-£500 (management), making comprehensive pet insurance a practical consideration.
