Your dog is experiencing a vestibular problem, a disruption of the system that controls his balance. The wobbliness of the eyes is called nystagmus. Affected dogs typically have a head tilt, wobbly gait or difficulty getting up. They also have a tendency to fall or roll to one side and may experience nausea and vomiting because the world seems upside down.
Vestibular disease can have a few causes-
- Ear infections- a severe ear infection can cause problems with the vestibulocochlear nerve.
Worth having your vet rule out but if your dog has no history of ear infections it's less likely.
- Idiopathic "old dog" vestibular disease- idiopathic means no one knows the cause. Some people believe that this is the result of a stroke, but there has been no evidence to show that this is the case. This is likely what is going on with your dog.
- Brain lesions, like inflammation or tumor. These are uncommon in dogs and tumors, though rare, would most often be found in older dogs.

Aside from having your vet rule out an ear infection, the most important treatment for this condition is nursing care. If he becomes nauseaous, he will need something for the vomiting. He will need to have his food and water brought to him if he's unable to get up. He may need to be carried outside if he's unable to get up on his own, and he may need puppy training pads to lay on if he has an accident.
The good news about old dog vestibular disease is that they do recover. Some dogs recover fully, others have a residual head tilt that causes no problems. It may take up to 2 weeks for him to get back to himself.
