WOBBLERS
Wobblers is a disease with many names; CVI – cervical vertebral instability, CVM – cervical vertebral malformation, CVMM – cervical vertebral malformation-malarticulation, and cervical spondylopathy just to name a few. Wobblers is primarily a disease of large and giant breeds. The cause of the disease is not well understood. It is believed to have a hereditary component but has not been proven to either.
The primary sign of wobblers is a “wobbly” or unsteady gait mostly in the rear. The wobbly gait may only be visible on slippery floors or when the dog walks slowly. Often times dogs walk with their heads down (a pain indication). In the more advanced stages of the disease the problems become obvious in all four legs, and they may have trouble getting up, appear very weak, and even “buckle over” with the front legs. Approximately 5% of dogs with wobblers may become acutely paralyzed in all four legs. This pain response is caused by the compression of the spinal cord as the disease progresses.
To diagnose the disease, your vet will utilize medical imaging typically xrays first to rule out diseases which can mimic wobblers and then a referral will be given to go and receive an MRI for confirmation. After diagnosis, there are two possible treatment options depending on the severity of the disease. Dogs can be treated medically or surgically. Medical management usually consists of the use of anti-inflammatory drugs (steroidals or non-steroidals) with restricted activity. Because they have a neck problem, neck leashes should not be used, and a chest harness is strongly recommended.
Based on a study completed at Ohio State involving 104 dogs we learned that approximately 50% of dogs will improve with medical management, approximately 30% will remain stable and 20% will worsen. Surgical treatment offered a success rate of approximately 80%. The other 20% of dogs either remained stable or worsened.
