"Your dog probably suffers from DM, Degenerative Myelopathy".
For my friend Thomas, the vets' verdict was like hearing a death-sentence.
After months of testing, x-rays, blood tests, and CAT scans, several vets couldn't find the cause why Cliff was dragging with his rear right leg. And when no diagnosis can be made, the final diagnosis is always, "it's probably DM". DM is only diagnosed, when everything else has been ruled out.
Thomas knew it was severe. Maybe one year, two at best, for Cliff to have some quality of life.
