Changes in a dog’s pupils can be an early warning sign of worsening brain disease, including meningitis, head trauma, or cardiac arrest. Veterinarians check pupil responses during every neurological exam, but these checks rely on visual judgment and can miss small yet important changes. This study will test whether a quick, automated, non-invasive device can measure pupil reactions more precisely. Ultimately, this approach could change how brain problems are detected and monitored, helping dogs receive faster and more accurate care when their neurological health is at risk.

This research focuses on improving a simple but essential part of the neurological exam: how a dog’s pupils respond to light. By improving the accuracy of this basic exam, we aim to help veterinarians recognize brain problems sooner, make better treatment decisions, and improve outcomes for dogs facing critical illnesses.
