Scotty Cramp In Dogs – Symptoms & Treatment

Scotty Cramp In Dogs

What Is Scotty Cramp In Dogs?

Scottie cramp is an autosomal-recessive, hereditary, neuromuscular disorder that affects a dog’s ability to move its limbs temporarily or intermittently. This affects Scottish Terriers (Scottie) and sometimes the West Highland White terriers, Cairn terriers, and Cesky terriers, especially those less than 18 months of age.

The disorder has unexpected episodes immediately following times of physical activity or stress, lasting up to 20 minutes. Affected dogs experience hyper-extension, stiff limbs, arching spine, muscle spasms, a “goose-stepping” gait, and a downward flexed tail.

Actually, Scottie's cramps are not cramps; these hyperkinetic episodes are caused due to temporary loss of CNS coordination and the muscles collect “inaccurate” transmission of serotonin from the nerve cells. Neurotransmitter serotonin plays a key role in the movement as well as in muscle contraction.

In most dogs, the hyper­kinetic episodes are alleviated by a short period of rest, but the signs would rapidly resurface if the provoking factors are not removed. When the dog carries out physical activities for a longer time or becomes excited, the level of serotonin transmitted to the muscles is not high enough to function properly, and this leads to cramps in Scotties. The episode will stop as soon as the dog relaxes for some time.

Causes And Diagnosis For Scotty Cramp In Dogs

1. Causes:

  • Scottie cramp in dogs is an inherited, autosomal recessive condition.
  • For the disease to be passed on to the litter, both the parents must be carriers of the ‘Scotty cramp’ gene.
  • The exact gene that causes the cramps has not been identified.
  • In other dog breeds, there are similar types of muscle movement diseases have been identified. Cocker spaniels, Dalmatians, Norwich terriers, West Highland white terriers, and wirehaired terriers. However, the genetic cause is different from Scottie's cramps.

2. Morbidity:

  • Cause: Genetic serotonin deficiency
  • Gender: This is more predominant in females rather than males
  • Onset: Juvenile onset (usually < 18 months)
  • Hereditable: Yes

3. Mortality:

There is no mortality associated with ‘Scotty cramps’ documented yet.

4. Diagnosis:

  • Complete blood count test (CBC)
  • Electromyography (EMG)
  • Serotonin antagonist (methysergide) test

5. Prognosis:

There is no cure for Scotty cramps but it can be managed well with proper diet and treatment. Most Scotties undergoing treatment will show improvement within a month after starting the treatment. The condition is not fatal and the lifespan of dogs is not affected.
