Exercise-induced collapse (EIC) is a genetic condition in dogs that causes progressive weakness and collapse after strenuous exercise. It is most common in Labrador Retrievers but can also affect other breeds like Cocker Spaniels, Corgis, German Wirehaired Pointers, and Old English Sheepdogs. EIC is characterized by muscle weakness, lack of coordination, and life-threatening collapse.
The onset of symptoms usually begins by the time the dog is 3 years old, and affected dogs typically tolerate mild to moderate exercise but experience collapse after about 5-20 minutes of intense activity. The severity of EIC varies, with some dogs continuing to move while dragging their hind legs and others becoming completely unable to move. While most dogs recover within 30 minutes, some may experience severe reactions that can be fatal. There are no medical treatments for EIC, but managing triggers and limiting exercise can help prevent episodes of collapse.
Key Takeaways:
- Exercise-induced collapse (EIC) is a genetic condition in dogs that causes weakness and collapse after intense exercise.
- EIC is most often seen in Labrador Retrievers, but other breeds can also be affected.
- Dogs with EIC typically tolerate mild to moderate exercise but experience collapse after intense activity.

Understanding EIC Genetics and Breeding
EIC, or Exercise-Induced Collapse, is an autosomal recessive genetic disorder that affects dogs. This means that dogs must inherit two copies of the mutated gene to be affected. Breeding a dog that has EIC with another dog that also has EIC will result in all the offspring being affected by the condition. Breeding an affected dog with a carrier will result in 50% of the offspring being affected, and 50% being carriers themselves. Breeding an affected dog with a clear dog will result in all the offspring being carriers, while breeding two carriers will produce 25% clear, 50% carriers, and 25% affected offspring.
Genetic testing is a crucial tool in the prevention of EIC. It can determine if a dog is affected, a carrier, or clear of the condition. By knowing the genetic status of their dogs, breeders can make informed decisions about breeding pairs, avoiding the production of affected puppies. Genetic testing is typically done through collecting DNA samples from the dog, such as cheek swabs or blood, and sending them to a specialized laboratory for analysis.
Breeding Outcomes for EIC
| Breeding Pair | Offspring |
|---|---|
| Affected x Affected | All Affected |
| Affected x Carrier | 50% Affected, 50% Carriers |
| Affected x Clear | All Carriers |
| Carrier x Carrier | 25% Clear, 50% Carriers, 25% Affected |
Genetic testing and responsible breeding practices are vital for reducing the prevalence of EIC. Breeders can utilize the information obtained from genetic testing to make informed decisions about their breeding program. By selecting breeding pairs that are clear of EIC or have low carrier rates, breeders can effectively reduce the risk of producing puppies affected by the condition. Organizations like the Orthopedic Foundation for Animals (OFA) provide a platform for breeders to share their dog’s genetic test results, promoting transparency and responsible breeding.
Symptoms and Triggers of EIC
Dogs with exercise-induced collapse (EIC) may exhibit various symptoms that can help identify the condition. One common symptom is weakness in the hind limbs, which can manifest as difficulty standing or walking. Lack of coordination is another sign to watch out for, as affected dogs may struggle to maintain balance or stumble while moving.
EIC triggers are activities that involve continuous intense exercise coupled with excitement or stress. Engaging in such activities can prompt a collapse episode in dogs with EIC. Examples of common triggers include playing ball, running, agility competitions, intense training sessions, and even playing with other dogs.
It is vital for dog owners to closely observe their pets for any abnormal walking patterns, weakness, or signs of distress during or after exercise. If any of these symptoms are noticed, it is crucial to discontinue the exercise immediately to prevent further collapse episodes or potential harm to the dog’s well-being.
Recognizing Symptoms
“Weakness in the hind limbs and lack of coordination are key indicators of EIC in dogs.”
Recognizing the symptoms and identifying triggers of EIC can help owners effectively manage their dogs’ exercise routines and prevent unnecessary collapse episodes.
