Overview

In the form described in Border Terriers, this syndrome causes episodes of involuntary muscle tightening and unusual movements. Dogs stay conscious but may be unable to use their legs normally during an episode. Between episodes, neurological examinations can be normal. Research in Border Terriers has linked the episodes to gluten sensitivity. Episodes may last minutes to hours and vary greatly in frequency.

Signs to watch for

  • Sudden muscle tightening or cramping
  • Unusual twisting movements or fixed limb positions
  • Difficulty standing or using the legs during episodes
  • Remaining awake and aware during the abnormal movements
  • Vomiting or soft stools in some affected dogs

Reported onset in Border Terriers ranges from early puppyhood to adult life.

When to get help Book a vet visit for repeated cramping episodes while your dog remains conscious.

Diagnosis and tests

Vets use the episode history and video recordings to recognize the movement pattern, then investigate other possible causes. Examination between episodes and brain scans may be normal. In Border Terriers, blood tests for antibodies linked to gluten sensitivity can provide supporting evidence alongside the clinical assessment.
