I dropped him off this morning at the neurologist's office for an MRI of his entire spine to diagnose the worsening problem. IF there is a solution it's likely to be surgery, and the prospect of that scares me. On the other hand, it's all he can do to hobble around.Our older dog has terrible trouble getting around on foot, but when he's in the water it's another story. He gets to swim in a very generous friend's pool several times a week. It's what's keeping him going.
