Clare actually does not advise crating for weeks -- indeed, she doesn't advise crating
at all once the dog is home
. Neurologists differ quite a bit on this issue. You can read her full advice on surgery on her website as she explains her approach.

It is also extremely rare for a dog to die right after surgery and few problems have been reported. The problem is medium to long term (as 80% of dogs improve right away after surgery as the pressure is gone) -- for some dogs it is that the symptoms return eventually because scar tissue ends up covering the area again and in worst case scenarios, come close to where the dog started. Most dogs don't have this degree of difficulty though even if they do get scar tissue.
For younger dogs with significant symptoms that signify a more severe case of SM, surgery is probably the only chance the dog may have for a medium to normal length life.
The statistics are worse for medications alone, all else being equal.
Much depends too on the type of syrinx, its shape, how fast the progression is... and so on.
Leo started to have symptoms at about 2.5 though he was diagnosed by MRI on a research scan (I was sure he was my 'clear' dog!). He needed gabapentin by about age 3. He has a large short syrinx that is in the centre of his spine -- lopsided large wide syrinxes tend to cause the most problems. Medication has managed his condition though he has gradually become more symptomatic. I keep his condition under review. In his case, Clare viewed his recent MRIs and thought if he was doing OK on medications that that was a better option for him.
A good neurologist familiar with SM can certainly give you advice on possibilities and advise on the basis of yur current MRI. For some dogs, that MRI may indicate surgery would be better than medication, and vice versa.
You can contact Stone Lion about having Clare give a second opinion on an MRI but it is better to bring your dog for a proper appointment if you are considering surgery, I think.
Most dogs that have surgery actually do really well, really quickly. the neurologists that advise long crating are the ones doing the mesh surgery which is far more involved than a basic decompression s screws are sunk into the skull, etc.
from Clare's website:
How successful is surgery?
Cranial/cervical decompression surgery is successful in reducing pain and improving neurological deficits in approximately 80% of cases and approximately 45% of cases may still have a satisfactory quality of life 2 years postoperatively (Rusbridge 2007). However surgery may not adequately address the factors leading to syringomyelia and the syrinx appears persistent in many cases (Rusbridge 2007). Much of the clinical improvement is probably attributable to improvement in CSF flow through the foramen magnum.
Should my dog have surgery or not?
The cases where surgery is clearly indicated and most likely to be considered successful are dogs that are painful and responding incompletely or not at all to medical management.
How long does it take a dog to recover from surgery for syringomyelia?
At Stone Lion Veterinary Centre postoperative dogs are hospitalised until the dog is comfortable enough for injectable painkillers to be discontinued. After discharge it typically takes 1-4 weeks before the dog returns to normal activity levels.
Will I need to confine my dog after surgery?
At Stone Lion Veterinary Centre postoperative dogs are not crate/cage restricted after discharge. Exercise is limited to short 5-10 minutes walks 2-4 times daily over the first 2 weeks postoperatively and then, depending on the dog’s progress, gradually increased over the next 4 – 8 weeks.
What is the recurrence rate after surgery?
In some cases scaring and fibrous tissue adhesions over the foramen magnum seem to result in re-obstruction and 25% to as many as 50% of cases can eventually deteriorate (Dewey et al 2005, Rusbridge 2007). This can be as early as 2 months postoperatively.
Will my dog need medication after surgery?
Even after successful surgery it is possible that your neurologist may recommend continuing some medication for example cimetidine or omeprazole to reduce cerebrospinal fluid production or painkillers because the damage to the spinal cord has resulted in a neuropathic pain syndrome.
