Details about the disease
EF is a neurological condition, induced by exercise, excitement or frustration, in which muscle tone increases. This means the dog is unable to relax its muscles, causing the dog to become rigid and falls over.
Clinical signs
Affected dogs usually start to demonstrate clinical signs before one year of age, with most cases having their first episode aged 4-7 months. Clinical signs vary in severity ranging from mild, occasional falling to freezing or seizure-like episodes lasting hours. Severity of the episodes can increase or decrease as the dog gets older. There is no standard pattern to the attacks.
How is it inherited?
The disease is described as a 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.
