Screening Scheme Description

DNA test - EIC
Exercise Induced collapse

Retriever (Labrador)

Details about the disease

This condition leads to a defect in nerve communication during intense exercise. In affected dogs, certain factors can trigger the collapse including type of exercise, temperature and excitement.

Clinical signs

Dogs clinically affected by EIC will show signs of leg weakness followed by complete collapse after 5-20 minutes of strenuous activity. The severity can vary. Severely affected dogs may collapse with mild exercise - other dogs only exhibit collapse episodes sporadically (occurring at irregular intervals). First clinical signs are usually noticed between 5 months and 3 years of age, but can appear later in life.

How it is inherited

The disease is described as an autosomal recessive condition. This means that a dog must inherit two copies of an abnormal gene (one from its mother and one from its father) before its health is affected. A dog that inherits only one copy of the abnormal gene (from its mother or its father) will have no signs of the disease, but will be a carrier and may pass the gene on to any offspring.
