Exercise-induced collapse (EIC) is a DNM1-related syndrome common in Labrador Retrievers. Episodes look dramatic but are often recoverable—yet they are easily confused with cardiac syncope or heat stroke. Genetic proof plus an episode diary (temperature, duration, recovery) protects dogs from misdiagnosis and unsafe training regimens.
Watch list
Symptom checklist
Weakness or wobbly rear limbs after 5–15 minutes of intense excitement
Collapse with a clear mind (usually non-epileptic)
Rapid recovery over 5–25 minutes with rest
Triggers: retrieve drills, hot weather, high drive play
DNM1 mutation positive or carrier status on genetic panel
Digital vault protocol
Emergency & longitudinal management
Store DNM1 genotype and counseling documentation
Build an episode log: ambient temp, activity type, duration, recovery time
Rule out cardiac and neurologic differentials; keep those workups adjacent
Modify training intensity; document what activity thresholds are safe
Share the EIC protocol with trainers, daycare, and competition organizers

Exercise-Induced Collapse in Labrador Retrievers — common questions
Intense retrieval or high-drive activity in genetically susceptible dogs can trigger ataxia and collapse that typically resolves with rest. Log ambient temperature, activity type, and recovery time for every episode.
Genetic EIC testing is widely used in Labrador lines. Store lab results and episode timelines before breeding or high-intensity sport commitments.
EIC usually follows heavy exercise and recovers with rest; cardiac syncope needs ECG/echo workup. Keep both neurology and cardiology differentials documented until ruled out.
