Scottie Cramp is a disease in Scottish Terriers causing spasms and hyperflexion and hyperextension of the legs.
A goose-stepping gait and arched spine are often seen, and the dog may turn somersaults as it runs.
[5] To diagnose Scottie Cramp, the veterinarian will perform a physical exam, a complete blood count, a biochemistry profile, and a urinalysis of the dog.
In affected dogs, this will block serotonin and increase the frequency and severity of the symptoms.
[7] Because Scotty Cramp is inherited, affected dogs and their parents and siblings should not be bred.
