Exercise-Induced Collapse
Exercise-Induced Collapse (EIC) is a hereditary neuromuscular disorder causing loss of muscle control and collapse after intense exercise.
Detailed Description
EIC is caused by a mutation in the DNM1 gene, affecting nerve signal transmission during strenuous activity. Affected dogs appear normal at rest but may collapse after 5–20 minutes of intense exercise. Collapse episodes are typically brief, and most dogs recover with rest, but severe cases can be fatal.
Common Symptoms
- Weakness after exercise
- Loss of coordination
- Collapse
- Dragging hind limbs
- Confusion
- Rapid recovery with rest
Management Options
- Avoidance of strenuous exercise
- Controlled activity
Frequently Asked Questions
Can EIC be cured?
No, but it can be managed by avoiding strenuous exercise.
Is EIC painful for the dog?
No, most dogs recover quickly and are not in pain during episodes.
Can my dog still be active with EIC?
Yes, with controlled, moderate exercise.
Should I breed a dog that is a carrier?
No, responsible breeding avoids carriers and affected dogs.
How is EIC different from heat stroke?
EIC occurs without overheating and resolves quickly with rest.
