Intervertebral Disc Disease in Sealyham Terriers

Sealyham Terriers can develop intervertebral disc disease, where the cushioning discs between vertebrae degenerate and herniate into the spinal canal. While most common in long-backed breeds, Sealyham Terriers carry genetic risk factors that make disc disease a concern, particularly in middle age.

Prevalence

Typical Onset

Symptoms to Watch For

If your Sealyham Terrier shows any of these signs, monitor closely and consult your veterinarian.

sudden yelping or crying out in pain
reluctance to move or hunched posture
weakness or wobbliness in hind legs
dragging one or both back feet
loss of bladder or bowel control
pain when picked up or touched along the spine

Risk Factors

  • •genetic predisposition to disc degeneration
  • •obesity — excess weight compresses spinal discs
  • •jumping on/off furniture
  • •stair climbing without support
  • •high-impact activities or rough play

Diagnosis

Neurological examination grades severity (Grade I-V). MRI is the gold standard for locating disc herniation. CT myelography is an alternative. Radiographs may show narrowed disc spaces but cannot visualize the spinal cord directly.

Treatment

Grade I-II: strict crate rest for 4-6 weeks, anti-inflammatory and pain medications, muscle relaxants. Grade III-V: emergency surgical decompression (hemilaminectomy or ventral slot) within 24-48 hours for best outcomes. Grade V with no deep pain perception: surgical prognosis drops to 50%. Post-operative physical rehabilitation is essential.

Prevention

Maintain lean body weight. Use ramps instead of stairs for predisposed breeds. Avoid high-impact jumping. Support the full body when picking up long-backed dogs. Harnesses instead of neck collars. No roughhousing that involves twisting the spine.

When to See a Vet

EMERGENCY: If your dog suddenly cannot walk, drags hind legs, loses bladder control, or screams in pain — this is a veterinary emergency. Hours matter. Delaying surgery beyond 48 hours dramatically worsens prognosis.
