Does the dog have a head tilt? If so he could possibly have canine vestibular disease. This is not all that uncommon in older dogs. It is not fatal, many improve over time. Google canine vestibular disease I did have a golden who my vets thought he had cvd. I thought he had a brain tumor. I was told that I was over-reacting. My dog died within six weeks of a brain tumor. If you can, get a brain MRI.
Take this animal to the vet. It could be an equlibrium problem, caused by a number of things.
