I recently notice my 14 year old beagle mix has one puffy red eye, it’s only red and puffy in the sclera. He hasn’t been acting different at all or acting in pain

Hey there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. What you are seeing is a condition called Chemosis (swelling of the conjunctiva). This can be caused from trauma, insect bites, allergic reactions, etc. If this does not resolve after 24 hours, I would have Charlie examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
