Description
Scottie cramp is a neuromuscular condition that has been recognised to occur in Scottish Terriers


Cause
Th
e cause is a disorder in serotonin metabolism that causes a deficiency of available serotonin in the brain and it is a genetically inherited autosomal recessive trait. For this reason affected individuals should not be used for breeding. The signs are caused by paroxysms of muscle hypertonicity...muscle cramps.


Breed Occurrence
The disease occurs in Scottish Terriers


Signs

Scottie Cramp may occur in puppies as young as 6 weeks of age and is usually first  recognised in young puppies. The disease affects the animals posture and locomotion with muscular spasms, hyperflexion and hyperextension of limbs :

  • Rigidity of the hindlegs 
  • Falling over when running
  • In severe cases the puppy may be unable to walk or run

Complications
None, except trauma when the animal falls over.


Diagnosis
Diagnosis is made based upon the clinical signs and breed of dog. Adose of methysergide can be given which blocks serotonin and increases the frequency and severity of symptoms


Treatment
Several forms of symptomatic treatment have been tried in these cases, including  :

  • Diazepam 0.5-1.5mk/kg by mouth three times daily
  • Methylsergide 0.1-0.6mg/kg by mouth - has its effects in 2 hours and lasts 12 hours.

Vitamin E has been suggested to be helpful in some cases (1)

Euthanasia may be recommended for severely affected cases.

Provet recommends that affected individuals are neutered and are not bred from  to try to eliminate the condition from affected  breed lines


Prognosis
Good, unless the affected animal is unable to walk.
