Symptoms of CM

Rosie Before CM Medication
Before medication for CM Rosie suffered from headaches, light sensitivity and was very withdrawn.

The symptoms of Chiari-like Malformation (CM) are very similar to Syringomyelia (SM):

  • Head pain/sensitivity
  • Spinal pain/sensitivity
  • Light sensitivity (squinting)
  • Restlessness
  • Withdrawn/quiet
  • Yelping when picked up
  • Reluctant to jump or climb stairs
  • Scooting

Like SM, some dogs may not show pain in any obvious way but they could be enduring any of the symptoms. If you suspect CM or SM and are unable to visit a Neurologist, please take this downloadable treatment plan to your vet:
