You're speaking to Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply.

I'm sorry to hear of this with your Pug. The two main differential diagnoses for such behavior are blindness and encephalopathy (brain disorder) and the two are not mutually exclusive.

Dogs circling to the right might have lost sight in the left eye and because he's bumping into things, there would be dimished sight in the right eye.

Unfortunately, it's more likely that his disorientation and circling (indicative of forebrain dysfunction) is a symptom of a change in mentation (mental status) as seen with encephalopathies (brain disorders) - the most common of which at his advanced age are brain tumors. Because he's a Pug, I also need to consider a particularly virulent form of encephalitis called necrotizing encephalitis or "Pug encephalitis". His vet will want to perform a careful physical and neurologic exam on your Pug and referral to a specialist veterinary neurologist (please see here: might be suggested as such a specialist is best equipped to perform the advanced testing necessary to clarify the etiology of your Pug's behavior. Cerebrospinal fluid tap and analysis as well as MRI are likely to be recommended.

Please respond with further questions or concerns if you wish.
