That's where we are with Otis. I had to go find your first post since I missed it - he drags his back feet also. As soon as the vet saw him walk when we brought him in he believed that's what it was. We did do the x-rays to rule out a couple other things he said it could possibly be (I've already forgotten). And that's what we were left with. We opted out of the MRI or I think there's a contrast x-ray they can do also that will show it that we didn't do either.Probably degenerative myelopothy, but a specific diagnosis would require xrays and an MRI, which I won't put her through at age 14.
